• #1 Schwannoma: What It Is, Causes, Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/17877-schwannoma

  Schwannomas grow slowly and may exist for years without any symptoms. […] As schwannomas can form in several different areas of your body, the symptoms vary greatly. Some people may have more symptoms than others, and they can range from mild to severe. […] Schwannoma symptoms can include: A visible lump that may feel tender when you put pressure on it. Numbness. Muscle weakness. Pins-and-needles feeling (paresthesia). Pain that’s aching, burning or sharp. […] Vestibular schwannomas can affect hearing and balance and/or cause ringing sensations (tinnitus). […] Tumors by your facial nerve can affect swallowing, eye movement and taste sensations or cause facial paralysis. […] Sciatic nerve schwannomas can mimic disk herniation with low back pain, with radiating pain down your leg. […] In general, the prognosis for schwannoma is usually good. In the majority of cases, the tumor doesn’t come back (recur) if it’s been totally removed.

  The symptoms of a schwannoma vary depending on its size, location, and associated nerve. For example, if it’s near a nerve in your arm, you may feel pain, weakness, or tingling in that arm. […] A visible or palpable lump can develop at the site of the schwannoma, especially if it’s growing near the skin. […] Other symptoms include: Intermittent or consistent pain in the area where the tumor is located (although not all schwannomas cause pain), Numbness and tingling sensations in the area of the affected nerve, Loss of sensation in the area of the affected nerve, Muscle weakness or changes in reflexes, Dizziness or balance problems, Hearing loss or ringing in ears. […] Schwannomas grow slowly, can exist for years without symptoms, and can be present in multiple locations. […] The prognosis for individuals with schwannomas is generally excellent, especially when the tumors are detected early and are accessible for surgical removal.

  https://braintumorcenter.ucsf.edu/condition/schwannoma-grade-1

  Signs and symptoms of a schwannoma depend greatly on the location of the tumor. For schwannomas forming on peripheral nerves that are not cranial nerves, common signs or symptoms include the following: […] Patients with vestibular schwannoma may experience different symptoms specific to the locations of these tumors: Loss of hearing on one side […] Buzzing or ringing in the ear […] Dizziness or loss of balance […] Facial numbness on one side (from compression of cranial nerve V) […] Facial weakness or paralysis on one side (from compression of cranial nerve VII). […] These symptoms result when the tumor compresses the vestibulocochlear nerve, disrupting its function in relaying auditory or balance information. If the tumor becomes large enough, it may also begin compressing other nearby cranial nerves. For instance, compression of the trigeminal nerve may cause facial numbness. Likewise, compression of the facial nerve can cause facial weakness or paralysis.

• #1 Schwannoma: Symptoms, Causes, Treatment, and More

  https://www.healthline.com/health/schwannoma

  Schwannomas usually don’t produce symptoms until they become large enough to put pressure on the nerves around them. You may feel occasional pain in the area that’s controlled by the affected nerve. Some other common systems include: a visible lump under the skin, sharp, aching, or burning pain, a pins-and-needles sensation, muscle weakness, numbness, nighttime pain in back or neck. […] Depending on where the schwannoma is, you may feel these symptoms in your face, arms, legs, or torso. Your symptoms may change as the tumor gets bigger. […] Many schwannomas occur on the nerve that connect your inner ear and brain. This is known as a vestibular schwannoma, or acoustic neuroma. In addition to the symptoms above, an acoustic neuroma can also cause: hearing problems in one or both ears, ringing in one or both ears, loss of coordination and balance. […] Most problems caused by schwannomas are the result of the tumor becoming large and putting pressure on nearby nerves.

• #1 Schwannoma – Overview – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/schwannoma/cdc-20352974

  A schwannoma is a type of nerve tumor of the nerve sheath. It’s the most common type of benign peripheral nerve tumor in adults. It can occur anywhere in your body, at any age. […] If you develop a schwannoma in an arm or leg, you may notice a painless lump. Schwannomas are rarely cancerous, but they can lead to nerve damage and loss of muscle control. See your doctor if you have any unusual lumps or numbness. […] In general, a schwannoma grows slowly. When a schwannoma grows larger, more fascicles are affected, making removal more difficult.

  https://www.mayoclinic.org/diseases-conditions/acoustic-neuroma/symptoms-causes/syc-20356127

  An acoustic neuroma, also known as a vestibular schwannoma, is a noncancerous tumor. The pressure on the nerve from the tumor may cause hearing loss and imbalance. […] Pressure from an acoustic neuroma can cause hearing loss, ringing in the ear and problems with balance. […] Symptoms of an acoustic neuroma are often easy to miss and may take years to develop. Symptoms may occur because of the tumor’s effects on the hearing and balance nerves. […] As the tumor grows, it may be more likely to cause more noticeable or worse symptoms. […] Common symptoms of an acoustic neuroma include: Hearing loss, usually gradually over months to years. In rare cases, hearing loss can be sudden. Hearing loss usually occurs on one side or is worse on one side. […] Rarely, an acoustic neuroma may grow large enough to compress the brainstem and become life-threatening. […] Early diagnosis of an acoustic neuroma may help keep the tumor from growing large enough to cause complications such as total hearing loss.

  Over 90 percent of patients with acoustic neuroma experience one-sided deafness, often accompanied by tinnitus the perception of noise or ringing in the affected ear. […] Dizziness and balancing problems may occur early in the growth of the tumour, and can worsen as the vestibular division continues to deteriorate. […] If large enough, the tumour may grow on other cranial nerves and cause facial numbness, weakness of the facial muscles or swallowing problems. […] Some people may experience an unsteady gait brought on by the pressure placed on the cerebellum. […] Acoustic neuromas that are very large may also cause headaches.

• #1 Pathomechanisms in schwannoma development and progression | Oncogene

  https://www.nature.com/articles/s41388-020-1374-5

  Schwannomas are tumors of the peripheral nervous system, consisting of different cell types. These include tumorigenic Schwann cells, axons, macrophages, T cells, fibroblasts, blood vessels, and an extracellular matrix. All cell types involved constitute an intricate tumor microenvironment and play relevant roles in the development and progression of schwannomas. […] Schwannomas derive from tumorigenic Schwann cells, caused by loss-of-function mutations of the Nf2 tumor suppressor gene. […] Antoni A tissue may transform into Antoni type B tissue during tumor progression. […] It has been shown that these transition zones display the highest proliferation indices compared with the pure A- or B-type areas, as well as a marked infiltration of phagocytic macrophages. […] Further evidence for the transition theory is provided by early experimental findings, showing that Antoni B tissue exhibits many histopathological features reminiscent of Wallerian degeneration following PNS injury.

• #1 Pathomechanisms in schwannoma development and progression | Oncogene

  https://www.nature.com/articles/s41388-020-1374-5

  The presence and activation of macrophages modulate the cellular behavior of their environment through the release of pro- and anti-inflammatory cytokines. […] The significance of macrophages for schwannoma formation and progression is further underlined by a positive correlation between macrophage infiltration and tumor growth. […] Existing evidence suggests that a multi-leveled nerve microenvironment needs to be considered in schwannoma biology, as instructive cues from axons, inflammatory signals from macrophages and failed regenerative processes contribute to their formation and progression.

  https://www.barrowneuro.org/condition/schwannoma/

  The outcomes of surgery or other treatments depend on the location of the tumor, its size, and whether it affects critical structures or nerve functions. […] For schwannomas in locations that make surgery more complex, such as vestibular schwannomas (also known as acoustic neuromas) that affect the nerves related to hearing and balance, treatment goals include maximizing tumor removal while minimizing impacts on hearing, balance, and facial nerve function. […] Even in these more complex cases, modern surgical techniques and other treatment modalities (like stereotactic radiosurgery) have significantly improved outcomes, allowing many patients to maintain a good quality of life.

• #1 Frontiers | Recurrences and progression following microsurgery of vestibular schwannoma

  https://www.frontiersin.org/journals/surgery/articles/10.3389/fsurg.2023.1216093/full

  Background: The treatment approach of vestibular schwannoma (VS) has seen a change in recent years, with a trend away from radical surgery towards preservation of cranial nerve function. A recent study reported recurrences as long as 20 years after complete removal of VS. […] A total of 28 patients experienced recurrences with significant differences in the three subgroups. The strongest predictor of recurrence was the extent of resection, with patients who underwent STR having an almost 10-fold higher risk of recurrence and patients who had undergone NTR having an almost 3-fold higher risk than those treated with GTR. More than 20% of recurrences (6/28) occurred after more than 5 years. […] The majority of recurrences occurs after 3–5 years. Nevertheless, a follow-up of at least 10 years should be carried out.

  Symptoms can get worse over time as schwannomas brain tumours increase in size, but the growth rate can vary significantly between one patient and another. […] Due to the wide-ranging function of peripheral nerves, the symptoms of a schwannoma tumour will depend upon where it has formed and what those nerves are controlling. […] Symptoms of schwannoma could therefore include: Hearing loss that becomes gradually worse, Tinnitus (ringing in the ear), Facial muscle weakness, numbness or pain, Persistent headaches, Dizziness, Vertigo, Weakness in the arms or legs, Balance issues, especially if walking in the dark or on uneven ground, Poor limb co-ordination (ataxia) on one side of the body, A hoarse voice or difficulty swallowing.

  Tumor size is not directly correlated to the symptoms experienced by the patient. […] Symptoms found by our acoustic neuroma doctors in New Jersey typically include: […] Facial numbness, weakness or paralysis can occur when the growth has affected the adjacent seventh cranial nerve which controls facial muscle functions. […] In rare occasions, an acoustic neuroma may grow large enough to press against the brainstem and cause life-threatening complications and neurological damage. The normal flow of fluid between the brain and the spine can also be interrupted, causing a buildup of fluid in the brain which may result in pressure on the skull.

  We report a case of a 65-year-old woman who presented with chest pain and cough. […] Although schwannomas are benign tumors, there are some very rare cases in which they can become huge and life-threatening. […] This case appears to be a rare and valuable instance where a benign tumor inexplicably grew significantly over a period of 10 years, leading to death due to reasons such as missed surgical timing resulting from the lack of follow-up and the presence of comorbid psychiatric illness. […] However, in some cases, tumors gradually become larger and seriously compress the neighboring mediastinal organs, leading to death. […] Therefore, a benign tumor should not be neglected, and if surgery is not possible at the time of diagnosis, a regular follow up is necessary, in order not to miss the right timing for surgery.

  The symptoms of VS vary but the most common are hearing loss and tinnitus. Other possible symptoms are imbalance, taste disturbance, headache, facial weakness, and/or facial numbness. […] In our experience, a not insignificant number of patients will also describe cognitive difficulties such as slow-thinking, memory lapse, or a non-specific brain fog. These can be some of the most troubling symptoms affecting patients with VS, but unfortunately, less is known about them because these symptoms can be vague and are also common in the general population. […] Cognitive symptoms can affect patients with untreated tumors or after treatment with surgery or radiation. Although the exact incidence of development of new symptoms after treatment is unknown, they may be common and transient after treatment. Occasionally, new or pre-treatment symptoms persist; in one study of patients who underwent surgery for VS, 7% of patients self-reported long-term difficulty concentrating in an open-ended questionnaire.

• #2 What is Acoustic Neuroma (Vestibular Schwannoma)? Symptoms, Risk Factors & Treatments | MD Anderson Cancer Center

  https://www.mdanderson.org/cancer-types/acoustic-neuroma.html

  Acoustic neuromas are rare, benign tumors that grow on the nerve for hearing and balance, called the vestibulocochlear nerve or the eighth cranial nerve. […] The tumors usually grow slowly and do not spread through the body. The average tumor growth is estimated at one to two millimeters per year. However, some tumors grow more rapidly. Approximately one-third of patients have tumors that dont seem to grow at all. A few tumors (1%-2%) get smaller without any intervention. […] Although acoustic neuroma is not cancer, tumors can be dangerous if they grow large and press against the brainstem or brain. […] Occasionally, patients develop additional challenges after treatment for acoustic neuroma, such as facial paralysis or loss of balance.

  Vestibular schwannoma symptoms usually appear slowly and the tumors grow slowly over a period of years. However, symptoms can also appear suddenly. […] When the tumor is only affecting the part of the vestibular nerve that affects hearing, the symptoms are related to hearing or balance such as ringing or buzzing in one ear (tinnitus), gradual hearing loss in one ear, a feeling of fullness in the ear, and balance problems. […] The trigeminal nerve, which controls muscles in the face, is next to the vestibular nerve. When a tumor grows large enough, it may cause pressure on the trigeminal nerve and cause weakness in facial muscles. […] Other vestibular schwannoma symptoms are: Headaches, Fatigue, Changes in thinking, Oral or swallowing issues. […] Sometimes these benign tumors grow large enough to put pressure on areas of the brain and may become life-threatening.

• #2 Schwannoma (grade 1) | UCSF Brain Tumor Center

  https://braintumorcenter.ucsf.edu/condition/schwannoma-grade-1

  Typically, schwannomas only occur on one side, resulting in symptoms that affect either the left or right side of the body. For example, loss of hearing on one side. In some rare cases, schwannomas can develop on both sides, which would cause symptoms affecting both sides of the body. […] Schwannomas are benign, slow-growing tumors that do not spread to other parts of the body. Patients with vestibular schwannomas usually have excellent outcomes. Radiosurgery has excellent results when treating small vestibular schwannomas and surgery is also typically sufficient to remove the tumor and alleviate any symptoms. Schwannomas also rarely recur after complete surgical removal. The goals of therapy are always to maximize the degree of tumor control, alleviate existing symptoms, and preserve normal nerve functioning.
