Meralgia parestezyczna
Diagnostyka i diagnoza
Meralgia parestezyczna to mononeuropatia wynikająca z uwięźnięcia lub podrażnienia nerwu skórnego bocznego uda (nervus cutaneus femoris lateralis), manifestująca się parestezjami, drętwieniem, pieczeniem lub bólem w przednio-bocznej części uda, nasilającymi się podczas stania lub chodzenia. Diagnostyka opiera się przede wszystkim na szczegółowym wywiadzie i badaniu fizykalnym, w tym na teście kompresji miednicy, który charakteryzuje się wysoką czułością (~95%) i swoistością (~93%). Badania obrazowe (RTG, CT, MRI, USG) oraz elektrofizjologiczne (EMG, badanie przewodnictwa nerwowego, SEP) pełnią rolę uzupełniającą, pomagając wykluczyć inne patologie, takie jak radikulopatia lędźwiowa czy guzy. W diagnostyce ultrasonograficznej zwraca się uwagę na zmiany kalibru nerwu, niewyraźne perineurium oraz unaczynienie wewnątrznerwowe. Blokada nerwu skórnego bocznego uda z użyciem środka znieczulającego miejscowo stanowi ważne narzędzie potwierdzające diagnozę, a brak efektu może sugerować inną etiologię dolegliwości.
Diagnostyka meralgia paresthetica (meralgia parestezyczna)
Meralgia parestezyczna (łac. meralgia paresthetica) to mononeuropatia spowodowana uwięźnięciem lub podrażnieniem nerwu skórnego bocznego uda (nervus cutaneus femoris lateralis), co prowadzi do charakterystycznych objawów czuciowych w przednio-bocznej części uda. Diagnostyka tego schorzenia opiera się głównie na wywiadzie, badaniu fizykalnym oraz w wybranych przypadkach na badaniach dodatkowych.12
Wywiad i badanie fizykalne
Podstawą rozpoznania meralgia paresthetica jest dokładny wywiad i badanie fizykalne. Lekarz podczas diagnozy zwraca uwagę na charakterystyczne objawy, takie jak: parestezje, drętwienie, pieczenie lub ból w przednio-bocznej części uda. Objawy te mogą się nasilać podczas stania lub chodzenia, a ustępować w pozycji siedzącej.345
W trakcie badania lekarz może poprosić pacjenta o wskazanie i obrysowanie obszaru dotkniętego dolegliwościami oraz szczegółowy opis charakteru bólu. Badanie obejmuje również ocenę czucia w zakresie unerwienia nerwu skórnego bocznego uda.67
Istotnym elementem badania fizykalnego jest test kompresji miednicy (ang. pelvic compression test), który cechuje się wysoką czułością (około 95%) i swoistością (około 93%) w diagnostyce meralgia paresthetica. Test polega na ułożeniu pacjenta na boku (stronie niezajętej) i wywieraniu nacisku na miednicę przez około 45 sekund. Pozytywny wynik testu wskazuje na meralgia paresthetica.8910
Dodatkowo wykonuje się badanie siły mięśniowej i odruchów ścięgnistych w celu wykluczenia innych przyczyn dolegliwości. W przeciwieństwie do radikulopatii lędźwiowej, w meralgia paresthetica nie występują deficyty motoryczne, ponieważ nerw skórny boczny uda jest nerwem wyłącznie czuciowym.1112
Badania obrazowe
Badania obrazowe nie są niezbędne do postawienia diagnozy meralgia paresthetica, ale mogą być pomocne w wykluczeniu innych przyczyn dolegliwości.13 Najczęściej stosowane badania obrazowe to:
- Zdjęcie rentgenowskie miednicy i stawu biodrowego – może pomóc wykluczyć inne schorzenia, takie jak guzy kostne czy zapalenia stawów. Zmiany charakterystyczne dla meralgia paresthetica nie są widoczne na zdjęciach RTG.1415
- Tomografia komputerowa (CT) – zalecana, gdy podejrzewa się guz lub inną patologię mogącą uciskać nerw.1617
- Rezonans magnetyczny (MRI) – może być pomocny w wykluczeniu patologii kręgosłupa lędźwiowego (np. przepukliny dysku), guzów w obrębie miednicy czy schorzeń urologicznych i ginekologicznych.1819
- Badanie ultrasonograficzne – coraz częściej stosowane zarówno w diagnostyce, jak i przy leczeniu meralgia paresthetica. USG pozwala na lokalizację miejsca uszkodzenia nerwu, wykluczenie guzów oraz jest pomocne przy wykonywaniu iniekcji diagnostycznych i terapeutycznych.2021
W diagnostyce ultrasonograficznej meralgia paresthetica charakterystyczne cechy obejmują: nagłą zmianę kalibru nerwu, niewyraźne perineurium, unaczynienie wewnątrznerwowe lub zwiększony przekrój poprzeczny nerwu.22
Warto zauważyć, że w Niemczech odsetek badań obrazowych w diagnostyce meralgia paresthetica wzrósł z 44% w 2005 roku do 79% w 2018 roku, co wskazuje na rosnące znaczenie tych metod diagnostycznych.23
Badania elektrofizjologiczne
Badania elektrofizjologiczne nie są rutynowo wykonywane w diagnostyce meralgia paresthetica, ale mogą być pomocne w przypadkach wątpliwych lub opornych na leczenie. Do najczęściej stosowanych badań należą:2425
- Elektromiografia (EMG) – mierzy wyładowania elektryczne w mięśniach, co pomaga ocenić i zdiagnozować schorzenia mięśni i nerwów. W przypadku meralgia paresthetica wyniki EMG są zwykle prawidłowe, ale badanie może być potrzebne do wykluczenia innych zaburzeń, gdy diagnoza nie jest jednoznaczna.2627
- Badanie przewodnictwa nerwowego – elektrody umieszczone na skórze stymulują nerw łagodnym impulsem elektrycznym. Badanie to pomaga zdiagnozować uszkodzenia nerwów. Często wykonuje się porównanie nerwu skórnego bocznego uda po obu stronach.2829
- Somatosensoryczne potencjały wywołane (SEP) – mogą być pomocne w diagnostyce meralgia paresthetica, choć ich wyniki nie zawsze są jednoznaczne, szczególnie u pacjentów z otyłością.3031
Badania wykazały, że amplituda potencjału czynnościowego nerwu czuciowego (SNAP) jest najbardziej wiarygodnym parametrem elektrofizjologicznym w diagnostyce meralgia paresthetica.32 Czułość badań elektrofizjologicznych wynosi około 81,3% dla somatosensorycznych potencjałów wywołanych i 65,2% dla badania przewodnictwa nerwowego.33
W Niemczech odsetek diagnostyki nieobrazowej, w tym badań potencjałów wywołanych i neurografii, wzrósł z 70% w 2005 roku do 93% w 2018 roku.34
Blokada diagnostyczna nerwu
Blokada nerwu skórnego bocznego uda z użyciem leku znieczulającego miejscowo jest ważnym narzędziem diagnostycznym w meralgia paresthetica. Ustąpienie bólu po iniekcji potwierdza diagnozę.3536
W niektórych przypadkach do lokalizacji nerwu podczas wykonywania blokady wykorzystuje się obrazowanie ultrasonograficzne, co zwiększa precyzję zabiegu.3738
Brak poprawy po blokadzie diagnostycznej może wskazywać na bardziej proksymalną przyczynę dolegliwości lub inną etiologię.3940
Badania laboratoryjne
Badania laboratoryjne nie są rutynowo wykonywane w diagnostyce meralgia paresthetica, ale mogą być zalecane w celu wykluczenia innych przyczyn dolegliwości lub zidentyfikowania chorób współistniejących, które mogą zwiększać ryzyko wystąpienia tego schorzenia.41
Najczęściej wykonywane badania laboratoryjne obejmują:424344
- Poziom hormonów tarczycy w celu wykluczenia niedoczynności tarczycy
- Poziom witamin z grupy B
- Poziom ołowiu
- Morfologię w celu wykluczenia anemii
- Badania w kierunku cukrzycy
- Profil witaminy D
Diagnostyka różnicowa
Diagnostyka różnicowa meralgia paresthetica obejmuje wykluczenie innych schorzeń, które mogą dawać podobne objawy, takich jak:454647
- Radikulopatia korzeni L2-L3 (przepuklina dysku lub stenoza kanału kręgowego)
- Choroba zwyrodnieniowa stawu biodrowego
- Zespoły bólowe mięśniowo-powięziowe (np. punkty spustowe w mięśniu pośladkowym średnim lub naprężaczu powięzi szerokiej)
- Patologie w obrębie jamy brzusznej, przestrzeni zaotrzewnowej lub miednicy
- Neuropatia cukrzycowa
- Guzy kości lub tkanek miękkich
Kluczowe w diagnostyce różnicowej jest właściwe rozpoznanie radikulopatii lędźwiowej, która w przeciwieństwie do meralgia paresthetica może objawiać się deficytami motorycznymi, zaburzeniami odruchów oraz zmianami widocznymi w badaniu MRI kręgosłupa lędźwiowego.4849
Wnioski diagnostyczne
Diagnostyka meralgia paresthetica opiera się przede wszystkim na dokładnym wywiadzie i badaniu fizykalnym. Charakterystyczny obraz kliniczny, obejmujący parestezje, drętwienie lub ból w przednio-bocznej części uda, bez deficytów motorycznych, jest często wystarczający do postawienia diagnozy.5051
Badania dodatkowe, takie jak badania obrazowe czy elektrofizjologiczne, są pomocne w wykluczeniu innych przyczyn dolegliwości lub w przypadkach, gdy obraz kliniczny jest nietypowy. Blokada diagnostyczna nerwu skórnego bocznego uda z użyciem środka znieczulającego miejscowo jest cennym narzędziem potwierdzającym diagnozę.5253
Należy pamiętać, że meralgia paresthetica może być czasem mylona z innymi schorzeniami, szczególnie z radikulopatią lędźwiową, co może prowadzić do opóźnienia w diagnozie i leczeniu. Właściwe rozpoznanie ma kluczowe znaczenie dla skutecznego leczenia i uniknięcia niepotrzebnych interwencji.5455
Rosnąca dostępność zaawansowanych technik diagnostycznych, takich jak wysokiej rozdzielczości ultrasonografia czy neurografia rezonansu magnetycznego, może przyczynić się do poprawy diagnostyki meralgia paresthetica w przyszłości.5657
Co istotne, około 85% pacjentów z meralgia paresthetica doświadcza poprawy po leczeniu zachowawczym, co podkreśla znaczenie wczesnej i trafnej diagnozy tego schorzenia.5859

In most cases, we can make a diagnosis of meralgia paresthetica based on your medical history and a physical exam. This can entail testing the sensation of the affected thigh, having you describe the pain, and perhaps asking you to trace the numb or painful area on your thigh. Additional examination including strength testing and reflex testing might be done to help exclude other causes for the symptoms. […] To rule out other conditions, we might recommend imaging studies. Although no specific changes are evident on X-ray if you have meralgia paresthetica, images of your hip and pelvic area might be helpful in excluding other conditions as a cause of your symptoms. […] If we suspect a tumor could be causing your pain, we may order a CT scan or MRI. Other potential diagnostic tests we might use include: Electromyography. This test measures the electrical discharges produced in muscles to help evaluate and diagnose muscle and nerve disorders. A thin needle electrode is placed into the muscle to record electrical activity. Results of this test are normal in meralgia paresthetica, but the test might be needed to exclude other disorders when the diagnosis isn’t clear.

Meralgia paresthetica is also known as lateral femoral cutaneous neuropathy and is characterized by paresthesias, numbness, dysesthesia, and occasionally pain in the anterolateral thigh. […] Symptoms are often exacerbated by standing or walking and are relieved by sitting. […] As the lateral femoral cutaneous nerve does not have any motor component, there is no weakness associated with this condition. […] Meralgia paresthetica has an incidence of 3:10 000 patients and is most common in middle-aged adults but can occur in all age groups. […] Compression of the lateral femoral cutaneous nerve typically occurs where it enters the leg near the inguinal ligament. […] It is usually unilateral, but up to 20% of patients can develop bilateral meralgia paresthetica. […] Most cases are idiopathic.

The diagnosis of meralgia paresthetica involves gathering and evaluating a medical history, and performing a physical examination. Blood tests, imaging tests, or diagnostic nerve blocks may be included. Additional testing may be performed to rule out other conditions. […] A physical exam may include tracing the exact location of pain and numbness. Strength testing, reflex testing, and sensation testing of the affected thigh can help with making a proper diagnosis of meralgia paresthetica. A pelvic compression test will likely be completed, which involves applying pressure on the thigh. This helps rule out other causes of symptoms. […] Certain imaging tests may include an X-ray of the pelvis or thigh. This can rule out a tumor. A computed tomography (CT scan) or magnetic resonance imaging (MRI) scan can look for nerve or spinal problems that are causing the symptoms.

Meralgia Paresthetica is a painful compressive neuropathy of the lateral femoral cutaneous nerve (LFCN), causing burning pain and paresthesia in the thigh. […] The clinical syndrome of meralgia parasthetica is well-defined, and further diagnostic studies may be unnecessary. […] In unresponsive cases, the diagnosis can be confirmed by NCS, which is considered the gold standard. […] A study of 45 patients found the pelvic compression test had a sensitivity of 95% and a specificity of 93.3% for meralgia paresthetica. […] Other differential diagnostic conditions for meralgia paresthetica include trigger point referral patterns (from the gluteus medius or TFL muscles); retroperitoneal, abdominal, or pelvic pathology; lumbar disc lesion; or diabetes.

Meralgia paraesthetica is usually an entrapment neuropathy of the lateral femoral cutaneous nerve (LFCN). […] The pelvic compression test is highly sensitive and the diagnosis can often be made with this test alone. […] Injection of the nerve with local anaesthetic will abolish the pain. Ultrasound is effective both for diagnosis and for guiding injection therapy. […] MRI neurography of the lateral cutaneous nerve may be used to assist in diagnosis. […] Very often the diagnosis is slow to be made. Pain in the lateral thigh can arise from the back or hip. It is important to consider the possibility of the diagnosis and to try deep palpation medial to the anterior superior iliac spine and extension of the hip. Injection with local anaesthetic appears to be a good test.

[…] Your doctor will review your medical history and symptoms, and based on this a physical examination will be performed that includes a pelvic compression test where your doctor will look for pain by applying pressure at different points in your thigh. Diagnostic tests can include the following: […] CT scan: Special x-rays are used to produce clear images of any damage present in the internal hard and soft tissue structures of the body. […] Electromyography: Special electrodes are used to record the electrical activity and detect any damage to the muscles or nerves.
- #12 Meralgia Paresthetica, skinny jean syndrome – Dr. William E. Morganhttp://drmorgan.info/clinicians-corner/meralgia-paresthetica-skinny-jean-syndrome/
Meralgia paresthetica (MP) is a sensory mononeuropathy which can produce pain or paresthesia of the anterior-lateral thigh. Normally it is the result of a focal entrapment of the lateral femoral cutaneous nerve (LFCN) as it travels under the inguinal ligament, but it can also be caused by external compression. This peripheral entrapment is relatively common and has been confused with nerve root lesions. […] The diagnosis of meralgia paresthetica is almost always a clinical diagnosis, versus a diagnosis based on objective observable technology. Diagnostics such as X-ray, CT, MRI, and diagnostic ultrasound can only rule out other conditions, but they cannot confirm the diagnosis of this malady. The diagnosis of MP can be made through history, presentation, examination, and clinical deduction. Particularly helpful in making the diagnosis is the pain distribution pattern, a clearly defined cause (like the physical pressure of body armor), and a positive Tinels sign of the LCFN or tenderness of the nerve where it emerges from under the inguinal ligament.
- #13 Meralgia Paresthetica – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK557735/
Plain radiographs are not required in the diagnosis, given a consistent history and physical exam. […] The clinician may consider blood tests if a metabolic etiology is suspected. […] Meralgia paresthetica is a typically benign and self-limited condition with frequent spontaneous remission. […] Treatment focuses on patient reassurance and ways to reduce pressure and irritation over the nerve and groin region. […] Patients should be reexamined with a repeat neurologic exam if symptoms persist beyond 1 to 2 months with conservative treatments, at which point anticonvulsants such as gabapentin, phenytoin, or carbamazepine may be helpful for treating the patients neuropathic pain. […] Surgery is rare but may be considered in chronic refractory cases and is performed via either a surgical release procedure with decompression of the LFCN or via a nerve transection procedure. […] Approximately 85% of patients with meralgia paresthetica report spontaneous recovery with conservative management.

The diagnosis is mainly based on typical symptoms combined with a positive response to an infiltration procedure. […] In atypical cases, electrophysiological testing, neurosonography, and magnetic resonance imaging can be helpful in establishing the diagnosis. […] Advances in imaging and neurophysiological testing have made the diagnosis easier to establish. […] Hypesthesia is the symptom most commonly reported in typical MP. […] While typical MP is diagnosed by clinical examination, atypically located symptoms require an extended diagnostic process. […] Magnetic resonance imaging (MRI) of the pelvis may help to exclude urogenital or gynecological conditions. […] The increasing availability of high-resolution ultrasonography is helpful both for diagnosis (localization of the nerve, increased accuracy of infiltration, exclusion of rare entities such as neurinomas) and for treatment (intraoperative nerve localization).

Meralgia paresthetica (MP) is a condition characterized by damage to the lateral femoral cutaneous nerve (LFCN), leading to sensory disturbances and pain in the anterolateral thigh. […] For diagnosis, it is important to take a thorough medical history and perform an appropriate physical examination. Although the diagnosis of meralgia paresthetica is essentially clinical, auxiliary diagnostic methods such as nerve conduction studies and ultrasound examination are useful complementary tools. […] Sensory nerve conduction studies are useful for confirming the diagnosis and determining the severity of LFCN damage. […] The advantages of ultrasonography are its general availability and quickness. This method is useful both for diagnosis (localizing the site of damage, ruling out neoplasms) and for treatment (localizing the nerve during injection).

The diagnosis of meralgia paresthetica (MP) is usually based on clinical symptoms and physical examination. […] The diagnosis of MP is usually based on the patients symptoms and physical examination. […] The sonographic diagnosis of MP may be achieved based on the following signs: nerve abrupt caliber change, indistinct perineurium of the nerve, intraneural vascularity, or increased cross-sectional area. […] Our results demonstrate that if one of these abnormal sonographic features is present, that is, nerve abrupt caliber change, indistinct perineurium of the nerve, intraneural vascularity, or increased CSA, MP can be diagnosed by ultrasound. […] The abrupt caliber change of the LFCN is the direct sign of nerve compression, and ultrasound can usually find fibrous tissue around the nerve. […] In summary, the sonographic diagnosis of MP may be achieved based on the following signs: abrupt caliber change, indistinct perineurium of the nerve, intraneural vascularity, or increased CSA.

The prevalence of meralgia paresthetica (MP), which is caused by compression of the lateral femoral cutaneous nerve (LFCN), has been increasing over recent decades. […] Our study aims to report on current diagnostic and therapeutic strategies as well as time trends in clinical MP management in Germany. […] Patients hospitalized in Germany between January 1, 2005, and December 31, 2018, with MP as their primary diagnosis were identified using the International Classification of Disease (ICD-10) code G57.1 and standardized operations and procedures codes (OPS).

A painful mononeuropathy of the lateral femoral cutaneous nerve (LFCN), meralgia paresthetica is commonly due to focal entrapment of this nerve as it passes through the inguinal ligament. […] The clinical history and examination is usually sufficient for making the diagnosis. However, the diagnosis can be confirmed by nerve conduction studies. […] The incidence of meralgia paresthetica in the general population has been reported to be 4.3 per 10,000 person years. […] A literature review of patients with meralgia paresthetica who were treated with neurectomy, neurolysis, or injection found the incidence of complete pain relief to be 85%, 63%, and 22%, respectively.

Meralgia paresthetica (MP), coined from the Greek words meros (thigh and algos), meaning pain, is a neurological disorder characterized by a localized area of paresthesia and numbness on the anterolateral aspect of the thigh. […] A coherent history and pertinent physical examination is essential in making the diagnosis; however, red flags such as tumor and lumbar disk herniations must be recognized and appropriately treated. While the diagnosis of MP is essentially a clinical diagnosis, sensory nerve conduction velocity studies are a useful adjunctive diagnostic tool.

Electromyography. This test measures the electrical discharges produced in muscles to help evaluate and diagnose muscle and nerve conditions. A thin needle called an electrode is placed into the muscle to record electrical activity. This test might be needed to exclude other disorders. […] Nerve conduction study. Patch-style electrodes are placed on your skin to stimulate the nerve with a mild electrical impulse. The electrical impulse helps diagnose damaged nerves. A comparison of the lateral femoral cutaneous nerve on each side may be performed. This test might be done primarily to exclude other causes for the symptoms. […] Nerve block. Pain relief achieved from anesthetic injection into your thigh where the lateral femoral cutaneous nerve enters into it can confirm that you have meralgia paresthetica. Ultrasound imaging might be used to guide the needle.

In most cases, we can make a diagnosis of meralgia paresthetica based on your medical history and a physical exam. This can entail testing the sensation of the affected thigh, having you describe the pain, and perhaps asking you to trace the numb or painful area on your thigh. Additional examination including strength testing and reflex testing might be done to help exclude other causes for the symptoms. […] To rule out other conditions, we might recommend imaging studies. Although no specific changes are evident on X-ray if you have meralgia paresthetica, images of your hip and pelvic area might be helpful in excluding other conditions as a cause of your symptoms. […] If we suspect a tumor could be causing your pain, we may order a CT scan or MRI. Other potential diagnostic tests we might use include: Electromyography. This test measures the electrical discharges produced in muscles to help evaluate and diagnose muscle and nerve disorders. A thin needle electrode is placed into the muscle to record electrical activity. Results of this test are normal in meralgia paresthetica, but the test might be needed to exclude other disorders when the diagnosis isn’t clear.

Meralgia paresthetica (MP) is a sensory mononeuropathy affecting the lateral femoral cutaneous nerve. Diagnosis is typically made clinically, often utilising multiple diagnostic aids such as imaging and electrophysiology. […] Diagnosis of MP is based on clinical examination, imaging and electrophysiology. There is no obviously superior diagnostic strategy for MP. […] Effective diagnosis of meralgia paresthetica (MP) requires a combination of clinical examination, imaging and electrophysiological assessments, with no single tool proven superior. […] The sensory nerve action potential (SNAP) amplitude is the most reliable electrophysiological parameter for diagnosing MP, but neither SNAP nor somatosensory evoked potentials (SSEP) is definitively superior in detecting pathology. […] The diagnosis of MP is predominantly made clinically. Despite its relative common occurrence, healthcare professionals often misdiagnose MP due to its clinical similarity with other conditions, i.e. lumbar radiculopathies.

Meralgia paresthetica (MP) is a sensory mononeuropathy which can produce pain or paresthesia of the anterior-lateral thigh. Normally it is the result of a focal entrapment of the lateral femoral cutaneous nerve (LFCN) as it travels under the inguinal ligament, but it can also be caused by external compression. This peripheral entrapment is relatively common and has been confused with nerve root lesions. […] The diagnosis of meralgia paresthetica is almost always a clinical diagnosis, versus a diagnosis based on objective observable technology. Diagnostics such as X-ray, CT, MRI, and diagnostic ultrasound can only rule out other conditions, but they cannot confirm the diagnosis of this malady. The diagnosis of MP can be made through history, presentation, examination, and clinical deduction. Particularly helpful in making the diagnosis is the pain distribution pattern, a clearly defined cause (like the physical pressure of body armor), and a positive Tinels sign of the LCFN or tenderness of the nerve where it emerges from under the inguinal ligament.
