ABSTRACT
Osteochondromas account for approximately 15% of all bone neoplasms and up to 30-50% of benign bone tumors. Intracranial osteochondromas are very uncommon and represent only 0.1–0.3% of all intracranial neoplasms. We reported a 25-year old previously healthy male presented with malaise, paresthesia, and weakness of the right extremities. The patient was referred to as magnetic resonance imaging (MRI) to confirm the demyelinating disease. Instead of multiple sclerosis, an extra-axial lesion with hemorrhage was suspected, and the patient was hospitalized. Computer tomography (CT) showed a well-circumscribed extra-axial lesion with calcification. The patient had an episode of seizures accompanied by severe morning headaches, dizziness, vomiting, and speech disorders. The patient underwent craniotomy with the excision of the tumor under the control of intraoperative magnetic resonance imaging. Few episodes of Jacksonian Seizures were observed during the surgery and after the procedure. After the surgery patient remained with only slight neurological deficits. Follow-up of the patient with clinical examination and imaging studies showed no evidence of any recurrence.
