What is an osteoid osteoma?
An osteoid osteoma is a noncancerous (benign) bone tumor. Each tumor usually measures less than 1 inch across. These tumors don’t grow or spread anywhere else in your body. Osteoid osteomas most often develop in the long bones of your body. These long bones include your shin (tibia) and thigh (femur) bones.
What is the life expectancy of someone with osteoid osteoma?
Osteoid osteoma is a noncancerous tumor in your long bones. This tumor often occurs in your shin and thigh bones. Providers diagnose these tumors with X-rays and bone scans. Osteoid osteomas may go away on their own. Providers also treat them with NSAIDs or surgery. Once treated, people with an osteoid osteoma usually live long, full lives.
What causes osteoid osteomas to form?
Researchers are still working to understand what causes osteoid osteomas to form. They seem to start with inflammation in the bone. When that occurs, blood vessels in the area start to expand and grow. Bone-producing cells called osteoblasts soon start to multiply.
Does osteoid osteoma show up on Xray?
Imaging of Osteoid Osteoma. Imaging usually is very typical: X-rays show new bone formation and sometimes a small lucent spot (smaller than 1.5 cm), which is defined as the nidus. Computed tomography (cat scan, CT) is even better suited to show the new bone formation and the nidus.
Can osteoid osteoma turn malignant?
Deterrence and Patient Education An osteoid osteoma is a benign bone-forming tumor that has no potential to become malignant. It classically causes severe pain at night relieved with nonsteroidal anti-inflammatory medications. Occasionally, it resolves without treatment.
Is osteoid osteoma benign or malignant?
An osteoid osteoma is a benign (non-cancerous), small tumor that usually grows in the long bones of a person's lower extremities. The thighbone is the most common location, although it can occur in the bones of the hand, and it sometimes occurs in the lower part of the spine.
Is osteoma a malignant Tumour?
Osteoma is a benign, slow growing bone forming tumor that consists primarily of well-differentiated mature, compact or cancellous bone.
What is the prognosis of osteoid osteoma?
Providers diagnose these tumors with X-rays and bone scans. Osteoid osteomas may go away on their own. Providers also treat them with NSAIDs or surgery. Once treated, people with an osteoid osteoma usually live long, full lives.
Can osteoblastoma become malignant?
Although osteoblastoma is considered a benign tumor, there have been very rare cases in which an osteoblastoma has transformed into a malignant (cancerous) tumor.
What is the difference between osteosarcoma and osteoma?
Osteoid osteoma is distinguished from osteosarcoma by its radiologic pattern, strict histologic circumscription, and lack of significant cytologic atypia, abnormal mitotic figures, or malignant cartilage.
Can benign bone tumors become malignant?
Certain benign tumors can spread or become cancerous (metastasize). Sometimes your doctor may recommend removing the tumor (excision) or using other treatment techniques to reduce the risk of fracture and disability. Some tumors may come back–even repeatedly–after appropriate treatment.
Do osteoid osteoma grow?
Osteoid osteomas tend to be small — less than 1.5 cm in size—and they do not grow. They do, however, typically cause reactive bone to form around them. They also make a new type of abnormal bone material called osteoid bone.
How common is osteoid osteoma?
Osteoid osteoma accounts for around 5% of all bone tumors and 11% of benign bone tumors. Osteoid osteoma is the third most common biopsy analyzed benign bone tumor after osteochondroma and nonossifying fibroma. Two to 3% of excised primary bone tumors are osteoid osteomas.
Should osteoma be removed?
While most osteomas are not painful nor do they pose a health risk, many individuals want the bony growth removed for aesthetic purposes. Some osteomas can grow and become large, which can affect facial appearance. Surgery is required to access the osteoma and carefully remove the growth underneath the skin.
Is osteoid osteoma rare?
Osteoid osteoma is a common benign tumor that usually develops in the long bones of the leg — the femur (thigh bone) and tibia (shin bone) – but can occur in any bone. In 7-20 percent of cases, osteoid osteoma occurs in the spine.
How long is recovery for osteoid osteoma?
After surgery, patients may spend up to a week in the hospital, and may require up to 6 months before they can return to normal activities.
What is the center of osteoid osteoma?
The center of an osteoid osteoma is the nidus. It consists of growing tumor cells, blood vessels, and cells that over time form bone. A bony shell surrounds the nidus. Usually, osteoid osteomas are small tumors that measure less than 1 inch across. They typically form in the long bones, especially the thigh (femur) and shin (tibia) bones.
What does osteoid osteoma look like on an X-ray?
X-rays can help your healthcare provider diagnose the osteoid osteoma. On an X-ray, the bony shell appears white and the nidus will appear dark.
What is the procedure to remove osteoid osteoma?
CT-guided drill resections and radiofrequency ablations are less invasive options. An interventional radiologist can do these procedures. Your care team will use a CT scan to precisely locate the osteoid osteoma. The healthcare provider will then use a special drill or heated probe to remove or destroy it.
Where do osteomas form?
They typically form in the long bones, especially the thigh (femur) and shin (tibia) bones. They may also develop in the bones of the spine, arms, hands, fingers, ankles, or feet. They can occur in other bones. But that is much less common. Osteoid osteomas tend to be painful.
Can osteoid osteomas be painful?
Osteoid osteomas tend to be painful. They cause a dull, achy pain that can be moderate to severe. The pain is often worse at night. Osteoid osteomas occur more often in men than in women. They typically occur in children and young adults up to about age 24. But they can occur at any age.
How long do you have to stay in the hospital for a tumor?
You may need to stay in the hospital for several days. You may need to work with a physical therapist even after you go home.
What cells are responsible for building bone?
Bone-producing cells called osteoblasts soon start to multiply. They lay down the building blocks for bone. Cells that break down bone, called osteoclasts, also become part of the osteoma. The growing tumor puts pressure on the surrounding bone. This hardens and forms a shell around the tumor.
Where is osteoid osteoma most commonly found?
Osteoid osteoma is a benign tumor of the bone. This tumor is most frequently found in the legs but may occur also at other bones in nearly any part of the body. Osteoid osteoma is a tumor of children and young adults, it is very rare in older adults over the age of 50. .
What is the best treatment for osteoid osteoma?
Treating the pain: The most significant symptom of osteoid osteoma is pain, this can be treated with aspirin, ibuprofen or other over-the-counter anti-inflammatory drugs. Some patients have relief from certain medications for a while, but then these medications stop working.
How far away from osteoid osteoma can you get radiofrequency?
If the tumor nidus is more than 1 cm away from these structures the procedure can usually be safely performed.

Symptoms. In most cases, osteomas do not cause symptoms. In fact, a person may not realize that they have a growth until a doctor examines the sinuses or the skull due to other health concerns the person has. The size and location of the osteoma may contribute to its potential symptoms. For example, smaller growths are less likely to cause symptoms.
Can osteoma be diagnosed with a CT scan?
According to Stanford Medicine, a CT scan of the bones is often enough to diagnose osteoma. In many cases, a biopsy is not necessary. However, there are several other ways to diagnose an osteoma, including MRI and X-ray scans.

Osteochondroma
Osteochondroma is the most common non-cancerous bone tumour. It starts in the tough, flexible tissue that lines the joints (cartilage). These tumours are usually found near the ends of the long bones in the legs, but can also grow in the pelvic bones or shoulder blades. Osteochondroma tumours are usually found in people up to the age of 40.
Osteoma
Osteoma is a non-cancerous tumour that is found in the bones of the paranasal sinuses and skull and the long bones of the legs and arms. Osteoma tumours don’t usually cause any symptoms, so they can be hard to diagnose. People who have more than one osteoma tumour may have an inherited disorder called Gardner syndrome.

Chondroblastoma and osteoblastoma
Chondroblastoma and osteoblastoma are 2 types of bone tumours that are intermediate tumours. This means that they are in between being non-cancerous and cancerous. While they can grow and spread to the surrounding tissues, they very rarely spread to other parts of the body. These tumours have only a small risk of becoming cancerous.
