  https://www.childrenshospital.org/conditions/bone-tumors-and-bone-cysts

  Bone tumors and bone cysts are types of abnormal growth within a bone. Most bone tumors and bone cysts are benign (noncancerous). […] A bone cyst is a fluid-filled area inside a growing bone. Most bone cysts develop in the long bones of the arms or legs. They often have no symptoms and go away on their own. However, some bone cysts weaken the bone and increase the risk of fracture. […] Different types of bone cysts include unicameral bone cysts and aneurysmal bone cysts.

  https://orthoinfo.aaos.org/en/diseases–conditions/unicameral-bone-cysts/

  Unicameral bone cysts do not cause symptoms and are discovered incidentally. […] Some cysts are discovered after the bone breaks. Because it causes no symptoms, a cyst can expand and weaken the bone, creating an area susceptible to fracture. A bone weakened by a cyst can break with just a minor injury. This type of fracture is referred to as a pathologic fracture. […] Less commonly, a patient may notice a painless bump if the cyst has caused the bone to enlarge in a local area.

• #1 Aneurysmal Bone Cyst (ABC): What It Is, Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/23413-aneurysmal-bone-cyst

  Common symptoms are changes in your arm, leg, pelvis or spine. Those changes may include: […] A lump that you can see and feel. […] Pain that may get worse very quickly. […] Swelling around the lump. […] An ABC on your spine that presses on your spinal nerves may cause: […] Numbness […] Paresthesia (tingling sensation) […] Muscle weakness […] Paralysis. […] The condition may keep your child’s bones from growing as they should. That may mean your child’s arm or leg bones may be shorter than their other arm or leg. […] An aneurysmal bone cyst can cause a bone fracture if the tumor grows large enough to weaken your bones. […] Aneurysmal bone cysts are highly treatable. But they come back in 1 in 5 people. Recurrence is most common within the first year after treatment.

  Signs and symptoms of an aneurysmal bone cyst can include persistent pain and swelling, a noticeable lump or deformity in the bone, decreased range of movement, weakness or stiffness in the affected body part, and the skin in the affected area being warm to the touch. […] If an aneurysmal bone cyst develops inside the spine, it can disrupt the normal working of the nervous system and cause additional symptoms, such as muscle weakness, a shooting pain in the arms or legs (sciatica), numbness or a tingling sensation in the arms and legs, and problems with bladder or bowel control. […] Although it happens less often than in unicameral bone cysts, aneurysmal bone cysts can also sometimes cause fractures in affected bones.

• #1 Unicameral Bone Cyst: Symptoms, Causes & Treatment

  https://my.clevelandclinic.org/health/diseases/22412-unicameral-bone-cyst

  Most children don’t have symptoms, but cysts can cause bone fractures. […] Usually, unicameral bone cysts are painless and found by chance on an X-ray taken for another reason. Pain and swelling can occur if the bone around the cyst fractures. […] Most children with unicameral bone cysts are asymptomatic or have mild symptoms close to where the cyst is located, such as slight pain, swelling, and tenderness. […] If the cyst causes the bone to fracture, symptoms include bruising, difficulty moving, pain, swelling, and a visible change in shape or alignment of the bone. […] Most unicameral bone cysts don’t cause symptoms and resolve on their own when a child is fully grown. […] If a child has symptoms, has had a fracture or is at risk of a fracture, effective treatments are available. Ongoing monitoring is important as cysts frequently recur after treatment, especially in very young children.

  A simple bone cyst is a solitary, benign, fluid-filled cyst that may be a single chamber or septated. […] Most cases present with mild to moderate pain. The rapid growth of lesions may mimic malignancy. […] Bone cysts are often asymptomatic and found incidentally on radiographs. Sometimes, they may present with pain due to repeated hemorrhages or pathological fractures. […] Most cases present with mild to moderate pain. The rapid growth of lesions may mimic malignancy. Spinal lesions may cause radicular pain or neurologic deficits. […] Mild to moderate pain, present for weeks to months, is the most common symptom that brings patients to the clinic. […] Pathological fracture is present in approximately 75% of cases of UBC at the time of presentation. […] Asymptomatic lesions with a low risk for pathological fractures/inactive cysts are usually left alone. Most children present with pain due to pathological fractures through cysts.

• #1 Aneurysmal Bone Cyst Clinical Presentation: History and Physical Examination

  https://emedicine.medscape.com/article/1254784-clinical

  Patients with an aneurysmal bone cyst (ABC) usually present with pain, a mass, swelling, a pathologic fracture, or a combination of these symptoms in the affected area. The symptoms are usually present for several weeks to months before the diagnosis is made, and the patient may also have a history of a rapidly enlarging mass. Neurologic symptoms associated with ABCs may develop secondary to pressure or tenting of the nerve over the lesion, typically in the spine. […] Pathologic fracture occurs in about 8% of ABCs, but the incidence may be as high as 21% in ABCs that have spinal involvement. […] Other findings may include the following: Deformity, Decreased range of motion, weakness, or stiffness, Reactive torticollis, Occasionally, bruit over the affected area, Warmth over the affected area.

  Unicameral bone cysts seldom cause symptoms. They may be discovered if a patient has a bone X-ray for an unrelated reason or if pain develops. […] Sometimes the cysts can grow, making the bone thin and weaker. Thinning of the bone can cause pain and makes it easier for the bone to break, this is called a pathologic fracture.

• #1 Unicameral Bone Cyst | Children’s Hospital of Philadelphia

  https://www.chop.edu/conditions-diseases/unicameral-bone-cyst

  Most children with a unicameral bone cyst will experience no symptoms. […] In most cases, unicameral bone cysts are only discovered when the child breaks the bone that has been weakened by the bone cyst. […] Unicameral bone cysts can cause the bone to be weak, and is most often diagnosed when a fracture occurs. […] At times, UBCs can prevent a limb from growing properly if they involve the growth plate. […] In rare cases, UBCs can cause limb length discrepancies, meaning, for example, one leg would be shorter than the other. […] UBCs may heal spontaneously by the time the child reaches skeletal maturity. […] Unicameral bone cyst tumors recur in up to 50 percent of cases even after treatment so it is important for your child to continue to see a doctor after treatment. […] In most cases, unicameral bone cysts will not recur after your child has reached skeletal maturity. […] The health outlook for children with unicameral bone cysts is good.

[…] In most cases, unicameral bone cysts will not recur after your child has reached skeletal maturity.

• #1 Aneurysmal Bone Cyst | Nationwide Children’s Hospital

  https://www.nationwidechildrens.org/conditions/aneurysmal-bone-cyst

  Most often the symptom that causes patients to realize that they have an ABC is pain in the affected bone. […] If left untreated, ABCs can be dangerous, especially if they are in a bone near a critical structure that might be injured should the bone break. This is especially true of ABCs in the skull or spine. […] If an aneurysmal bone cyst is left untreated, the destructive tumor processes in the bone continues. Further bone destruction will cause pain, fracture of the bone, immobility of the patient, and if the cyst involves the spine, further destruction can result in nerve damage or paralysis. ABCs are not known to go away without treatment.

  Spinal aneurysmal bone cyst (ABC) is a rare benign bone lesion with various prognosis. Common clinical symptoms of spinal ABCs include local pain, swelling. […] A unique aspect is that this patient did not have symptoms before she fell down on her hip, and had an acute worsening of her neurological deficits. […] Common clinical symptoms of spinal ABCs include local pain, swelling, muscle stiffness, and movement restriction; they are generally found a few months after symptom presentation. Neurologic deficit may happen with the infiltration and compression of nerve roots or spinal cord. However, some spinal ABCs do not have obvious symptoms until sudden causes happen, such as trauma, which may lead to pathological fracture. […] In this case, a unique aspect is that our patient did not have symptoms before she fell down on her hip, and had an acute worsening of her neurological deficits.

  https://www.webmd.com/osteoarthritis/subchondral-bone-cyst

  The cysts themselves dont seem to cause symptoms. But in rare cases, they can push on soft tissue in the area. That can cause pain. […] More often, if you have pain, it’s due to the osteoarthritis that causes the cysts. The pain tends to come and go at first. But it gets worse over time, or if you’re very active. It might be especially serious when you wake up. Eventually, the pain can become constant. […] As OA gets worse, stiffness and swelling can make it harder for your joints to work the way they should. You might also feel weaker over time — so much so that it gets harder to do simple things, like open a jar or bend down. […] Over time, the cyst itself can start to damage your joint. That can keep you from being able to make some movements.

  Primarily developing in children and adolescents, a unicameral bone cysts, also called a simple bone cyst, is a common, noncancerous (benign) bone tumor. […] Most unicameral bone cysts do not cause symptoms and are discovered by unrelated problems such as a broken bone. In some cases, a painless bump may be discovered. […] As the bone grows, the shape and size of the cyst can change. When the child stops growing, so will the cyst. Gradually, it will fill in with normal bone and disappear. […] Regardless of treatment method, unicameral bone cysts come back 25 to 50 percent of the time in the same place. Your physician will schedule regular X-rays to monitor the reoccurrence. Once a child is full-grown, these cysts typically stop growing and heal.

  This retrospective study evaluated the efficacy of minimally invasive surgery to control cyst progression for active unicameral bone cysts (AUBC) by intracystic methylprednisolone injection, percutaneous curettage, and autogenous bone marrow grafting. […] UBC are frequently asymptomatic and may regress spontaneously, but they are typically discovered incidentally or after a fracture. […] The long axis of active unicameral bone cysts (AUBC) is consistent with the longitudinal axis of the bone shaft; conversely, its transverse diameter is often narrower than that of the epiphyseal plate, making it unlikely for them to regress and prone to damage the epiphysis, resulting in a higher risk of fracture and the risk of skeletal deformity during curettage. […] For AUBC, minimally invasive treatment is feasible to control cyst progression and then cure it without sequelae. Intracystic methylprednisolone injection, percutaneous curettage, and autogenous bone marrow grafting are an excellent choice.

  Aneurysmal bone cysts usually develop before people reach age 25, and the cause is not known. These cysts tend to grow slowly. Pain and swelling are common. The cyst may be present for a few weeks to a year before diagnosis. […] The cysts often cause nearby bones to thin, which can lead to a break (fracture). Cysts that are less than 2 inches (about 5 centimeters) long or wide may heal and may disappear as the fracture heals. Cysts that are more than 2 inches long or wide, particularly in children, may require treatment. However, a better predictor of the risk of fracture is a cyst size greater than 85% of the diameter of the bone or a bony shell less than 0.5 millimeters. […] Regardless of treatment, the cyst remains or returns in about 10 to 15% of people.

  The aneurysmal bone cyst (ABC) is a benign expansile osteoclastic giant cellrich bony neoplasm composed of numerous blood-filled channels and cystic spaces. It most often affects individuals during their second decade of life and may occur in any bone in the body. Although benign, the ABC can be locally aggressive. Its expansile nature can cause pain, swelling, deformity, disruption of growth plates or joint surfaces, neurologic symptoms (depending on location), and pathologic fracture. […] The prognosis for an ABC is generally excellent, though some patients need repeated treatments because of recurrence, which is the most common problem encountered when treating an ABC. The overall cure rate is 90-95%. A younger age, open growth plates, and a metaphyseal location all have been associated with an increased risk of recurrence.

  Bone cysts are a condition that frustrate horse owners, and although they are a relatively common occurrence, how and why they develop is still not fully understood or agreed upon. […] The typical history of a horse with a bone cyst is intermittent lameness of varying severity which appears when the horse begins training or following increased intensity of training. The lameness usually decreases or resolves with rest. The affected joint may also show evidence of swelling but this is difficult to detect in the stifle joint. […] If trauma occurs to a joint during a period of rapid growth damage to the cartilage can occur. Similarly damage to a mature joint can compromise the integrity of the underlying articular bone and can form a bone cyst. […] The diet of young growing horses has been shown to have a direct link to the development of bone cysts.

  https://mdsearchlight.com/joint-muscle-and-bone/aneurysmal-bone-cysts/

  Aneurysmal bone cysts are non-cancerous growths that look like tumors and are filled with blood. They can show up in any bone, but are most often found in the thigh bone, shin bone, or backbone. These cysts can cause the bone to swell, leading to pain, inflammation, joint disruption, and damage to areas of the bone responsible for growth. Sometimes, they can grow swiftly, damage the surrounding bone tissue, and make the bone so weak that it fractures. […] People with an aneurysmal bone cyst often experience a slow onset of pain that develops over weeks or even months. This pain might be coupled with swelling or a lump that can be felt. However, some people first become aware of the problem when they suddenly experience pain due to the cyst causing a pathological fracture. If the cyst presses against a nerve or involves the spine, neurological symptoms may occur.

  The presence of the simple bony cyst is a rare condition in the foot. […] The simple bone cyst (QOS) of the calcaneus is a benign and very rare lesion. It has a pseudotumoral character that can sometimes grow and dilate the cortex, even breaking it. Its diagnosis is usually casual or due to the appearance of pain, sometimes accompanied by swelling. […] The pain from this injury is due to trabecular and cortical fractures. It usually occurs when the size of the cyst is greater than 1/3 of its mass. […] The size of the cyst can cause the collapse of the subtalar joint, so due to the age of the patient the surgical treatment is indicated to avoid permanent deformities in the architecture of the foot that cause chronic painful sequelae in walking. […] The activity of the bony cyst diminishes as the person matures skeletally and as the body growth ends, this way it does not spread further, spontaneously and slowly reinforcing the cortical cover, not recurring the lesion if has made a correct treatment.

  The aneurysmal bone cyst (ABC) is a benign expansile osteoclastic giant cellrich bony neoplasm composed of numerous blood-filled channels and cystic spaces. It most often affects individuals during their second decade of life and may occur in any bone in the body. Although benign, the ABC can be locally aggressive. Its expansile nature can cause pain, swelling, deformity, disruption of growth plates or joint surfaces, neurologic symptoms (depending on location), and pathologic fracture. […] The prognosis for an ABC is generally excellent, though some patients need repeated treatments because of recurrence, which is the most common problem encountered when treating an ABC. The overall cure rate is 90-95%. A younger age, open growth plates, and a metaphyseal location all have been associated with an increased risk of recurrence.

  Aneurysmal bone cysts are non-cancerous growths that look like tumors and are filled with blood. They can show up in any bone, but are most often found in the thigh bone, shin bone, or backbone. These cysts can cause the bone to swell, leading to pain, inflammation, joint disruption, and damage to areas of the bone responsible for growth. Sometimes, they can grow swiftly, damage the surrounding bone tissue, and make the bone so weak that it fractures. […] People with an aneurysmal bone cyst often experience a slow onset of pain that develops over weeks or even months. This pain might be coupled with swelling or a lump that can be felt.

[…] Aneursymal bone cysts expand and deform the involved bone. In some cases, this can lead to damage to joints or pathological fracture (a fracture that occurs without trauma). They also cause pain and swelling around the site of the cysts and do not generally go away on their own. […] Aneurysmal bone cysts return about 20 percent of the time. To treat cysts that return, our doctors provide follow-up care for every three months for the first two years after treatment. Recurrent aneurysmal bone cysts are treated using the same techniques, although your child’s orthopedic surgeon may opt for a more aggressive treatment to prevent further recurrence.
