Primary chondrosarcoma of skull base presenting as subarachnoid hemorrhage

Chondrosarcoma (CSA) is a significant uncommon tumor and tends to be located in the extremi-ties. When it affects the skull base, can be manifested in several ways. We report a case of a CSA in a 21-year-old male patient who presented with headache and neck stiffness. Radiological evaluation revealed a destructive mass in left temporal fossa with surrounding subarachnoid hemorrhage. The angiography was performed with no vascular anomaly. Biopsy of the mass showed characteristic features of a conventional CSA. To the author’s knowledge this is the first report of a skull base chon-drosarcoma presenting with subarachnoid hemorrhage. This case highlights the rarity of this tumor with regard to unusual clinical presentation.
