p class="abstract">Osteomas are benign mesenchymal osteoblastic tumors of lamellar bones. In our practice, they are usually seen in the paranasal sinuses, mainly involving the frontal and ethmoidal sinus. Osteoma of the temporal bone is uncommon and when they occur, they are most commonly seen in the external auditory canal. Mastoid osteomas are a...

Osteoblastoma is a benign bone tumour arising from the non-odontogenic epithelium. This tumour predominantly affects the vertebral column and long tubular bones such as the femur and tibia. Herein, we report a case of Osteoblastoma affecting temporal bone. Radiologically, it was thought to be an intraosseous meningioma, hemangioma, or eosinophilic...
