The diagnosis of an intra-articular osteoid osteoma can be a challenging and lengthy process, with reports of delayed diagnosis of greater than 2 years. In the young, athletic patient with an atraumatic onset of groin pain, an overuse injury or muscle strain is the most likely etiology. However, an overuse injury of femoral neck stress fracture must be identified because of the potentially disa...

Osteomas are benign, slow-growing tumors that most frequently occur in the craniomaxillofacial region. These tumors are mostly asymptomatic and are generally found incidentally. A giant osteoma is generally considered to be greater than 30 mm in diameter or 110 g in weight. A 35-year-old female presented to us with complaints of a firm mass that showed continuous growth on the forehead followin...

Osteoma is a benign, slow-growing tumor characterized by proliferation of compact or cancellous bone. It is perhaps the most common benign tumor of the sinonasal system.1 Radiologic evidence of osteoma can be present in up to 1% of all radiographs2 and up to 3% of all CT scans.3 In up to 95% of the patients the osteoma is situated in frontoethmoidal region. Osteomas of the maxillary sinus repre...

INTRODUCTION Mastoid osteoma is a rare benign tumour. In this article, the authors report two new cases of mastoid osteoma and discuss the modalities of diagnosis and management. CASE REPORTS Both patients presented with a retroauricular mass that had been slowly increasing in size over several years. The patients consulted for the cosmetic deformity induced by the lesion or moderate tenderne...

In this study, an unusual case of osteoma is presented, whereby a bone marrow osteoma was identified in the tibia. No previous cases of bone marrow osteoma have been reported. In this case, an eight-year-old male presented with discontinuous discomfort in the right distal calf for six months. Radiological examination and computed tomography revealed a radiopaque lesion within the affected bone....

Choroidal osteoma is an uncommon benign osseous intraocular tumor that typically affects young adult women. Choroidal neovascularization (CNV) is one of the complications that can develop in eyes with choroidal osteoma. We present a case of CNV secondary to choroidal osteoma treated with intravitreal ranibizumab. A 57-year-old lady presented with painless loss of vision with a right-eye visual ...

Primary osteoma cutis is characterized by the formation of normal bone tissue in the dermis or subcutis without any underlying tissue abnormality or pre-existing calcification. This illness is associated with Albright hereditary osteodystrophy (AHO), which is characterized by such physical features as a short stature, round face, obesity, brachydactyly and osteoma cutis. Pseudohypoparathyroidis...

Although a few cases of osteoma in renal pelvis and urinary bladder have been reported, no cases of osteoma in the testis have been presented. A case of so-called osteoma of the testis incidentally found in a 30-year-old man was presented with discussion for its histogenetic considerations.

A case of choroidal osteoma presenting during pregnancy is reported. The clinical findings are summarised and the features of choroidal osteoma are discussed.

Osteoma is the most common benign tumour of the nose and paranasal sinuses. However, involvement of the sphenoid sinus by osteoma is rare. Most of the time, patients with paranasal sinus osteoma are asymptomatic. However, symptoms may present, depending on the location and extension of the tumour. We report a case of a patient with sphenoethmoidal osteoma found incidentally on imaging, with evi...
