Osteoma is the most common benign tumor of the paranasal sinuses. Turbinate osteomas are very rare and only four middle turbinate, one superior turbinate and one inferior turbinate osteoma cases have been reported. We present a rare case of osteoma of the left middle turbinate in a patient presented with unilateral nasal obstruction and epiphora that was removed endoscopically, and conduct a li...

In case of intra-articular osteoid osteoma, misdiagnosis as juvenile arthritis may occur, delaying adequate treatment. We report cases of intra-articular osteoid osteomas in children that were misdiagnosed and initially inappropriately treated with intra-articular corticoid injection. Diagnosis of osteoid osteoma was finally given by CT-scan and appropriate treatment by radiofrequency ablation ...

We present a case of osteoid osteoma with a history of mild pain, local swelling and point tenderness on the right lower leg. The diagnosis of osteoid osteoma was difficult due to the atypical clinical history and misleading radiological and bone scan findings. When it is difficult to differentiate an osteoid osteoma from osteomyelitis using CT, MRI or bone scan; HIG scintigraphy can be used to...

A long-term follow-up of three patients suffering from osteoid osteoma who have not undergone surgery is reported. Only eight similar cases have been reported in the literature. It is shown that over a period of years the pain of osteoid osteoma eventually disappears but the radiological appearance may remain unaltered or gradually resolve. Surgical management of osteoid osteoma is advised beca...

Osteoid osteoma is an uncommon benign tumor and causes severe pain, being worse at night, that responds dramatically to nonsteroidal anti-inflammatory medications. An osteoid osteoma of the toe is very rare and arising in a pedal phalanx may be difficult to diagnose. A 34-year-old male has local swelling and tenderness but there were no hyperemia, temperature increase, or clubbing. There was a ...

Purpose: Choroidal osteoma is a rare tumor which features intraocular bone formation. This tumor can be complicated by choroidal neovascularization which is a cause of impaired vision in this condition. We present a case of choroidal osteoma with choroidal neovascularization as a complication. Methods: Case report with clinical and angiographic correlation. Results: A 16 year old female present...

STUDY DESIGN Case report and systematic review of the literature. OBJECTIVE To describe a rare case of remodeling of the cervical facet joint after the microendoscopic resection of an osteoid osteoma.

Spinal tumors consist of a large spectrum of various histologic entities. Multiple spinal lesions frequently represent known metastatic disease or lymphoproliferative disease. In solitary lesions primary neoplasms of the spine should be considered. Primary spinal tumors may arise from the spinal cord, the surrounding leptomeninges, or the extradural soft tissues and bony structures. A wide vari...

Osteoma cutis or cutaneous ossification is a rare entity characterized by the formation of bone in the skin. We present an isolated primary osteoma cutis located on the palm, an atypical location.

osteoid osteoma is a benign bone tumor that when located on the base of the coracoids process of the scapula is very rare and diagnosis and treatment is often delayed because of its rarity. almost any bone can be involved, but half of cases involve the femur or tibia. the radiologic features of osteoid osteoma are well known, but these tumors may present with unusual features and be easily misd...
