Cavernous sinus tumors: neuroradiologic and neurosurgical considerations on 150 operated cases.

We reviewed the neuroimaging studies of 150 patients with cavernous sinus tumors operated on during an 8-year period. Meningiomas (66 cases), chordomas (18 cases), trigeminal neurolemmomas (12 cases), and chondrosarcomas (11 cases) were the most common diagnosed neoplasms. Neuroradiological findings are briefly described for each different kind of tumor encountered. The surgical impact of these findings is discussed.
