Intracranial Intraparenchymal Ostemoa: Case Report

A 55-years-old woman suffered from 5 years of persistent left temporo-parietal headache. She had no feature of raised intracranial pressure. Her headache was only partially relieved by analgesics. There was no history of head trauma nor systemic disease. Plain radiographs of the skull showed a dense round opaque lesion in the left parietal area. Computed-Tomography showed a hyperdense lesion in the same region suggestive of an osteoma. In operation, we found the bony hard mass in the subarachnoid space to be unattached to the dura or the skull. The mass was totally removed, and histologically it was an osteoma.
