An ostoid osteoma is a vascular lesion consisting of an area of immature bone surrounded by osteoblasts and osteoclasts.

Definition/Description[edit | edit source]

Benign osteoblastic tumor consisting of vascular osteoid tissue centrally and sclerotic bone peripherally. This type of tumor is commonly found in the diaphysis of long bones such as the femur (more than 50% of cases). This type of tumor can also occur more rarely in the bones of the hands, feet, and posterior spine.[1][2]

Prevalence[edit | edit source]

Osteoid osteomas account for 1/8 to 1/10 of symptomatic bone tumors and 5% of all primary bone tumors.[3]

Osteoid osteomas occur in children and young adults between the ages of 7 and 25. This type of bone tumor also occurs two to three times more often in males than in females.Cite error: Closing </ref> missing for <ref> tag. Another reason diagnosis is easily misled is that pain usually occurs before the lesions are visible on radiographs and in the early stages can be easily missed on a radiograph.[4] Finally, these lesions may be associated with proliferative synovitis due to prostaglandin secretion that decreases range of motion, creates joint effusion, and can mimic inflammatory arthritis.[5]

Associated Comorbidities
[edit | edit source]

None

Medications[edit | edit source]

Pain caused by osteoid osteomas can be relieved with aspirin and NSAIDS, which inhibit the prostraglandins released by the tumor cells. Prostaglandins cause changes in vascular pressure, which stimulates sensory nerve endings locally, causing pain. Inhibition of these prostaglandins relieves pain.[1][6]

Diagnostic Tests/Lab Tests/Lab Values[edit | edit source]

Radiograph reveals a well demarcated area of translucency (nidus) inside the bone, often times with a central calcified dot. This is surrounded by bony sclerosis. Usually less than 1 cm in size www.uhrad.com/msiarc/msi084.htm An osteoid osteoma can also be detected with bone scan, or scintigraphy, which will show a focal uptake of the radiotracer by the tumor. Cintigraphy is often used to detect an osteoid osteoma that is not easily seen on a radiograph, such as a vertebral tumor.[1]Osteoid osteomas can be detected on an MRI and CT scan, which are often used to identify the location of the nidus when the tumor is intra-articular. A CT scan will reveal the nidius as a small area of low attenuation surrounded by reactive bone formation, seen as a larger area of higher attenuation.[6]

Causes /[edit | edit source]

An ostoid osteoma is a vascular lesion consisting of an area of immature bone surrounded by osteoblasts and osteoclasts. The tumor starts with the nidus, or nest of vascular osteoid tissue in the center of the tumor. The nidus then becomes surrounded&nbsp;by reactive bone sclerosis. After the removal of the nidus, the secondary bone sclerosis generally disappears gradually.[6]

Systemic Involvement[edit | edit source]

Systemic involvement is uncommon with an osteoid osteoma.[6]

Medical Management (current best evidence)[edit | edit source]

Treatment options include medical management with NSAIDs, surgical excision (wide/enbloc excision or curetting), or the use of CT- or MRI-guided minimally invasive procedures including core drill excision, laser photocoagulation, or radiofrequency ablation. For many years, complete surgical excision was the classic treatment of osteomas, usually performed in patients with pain despite medical management.
