Abstract:
We present the CT, MR angiographic, and histologic findings of a rare primary meningeal melanocytoma of the cavernous sinus. The primary differential diagnosis is between a melanin-containing tumor and an extraaxial cavernous angioma. Radiologic imaging cannot distinguish between the less aggressive primary meningeal melanocytoma and the more aggressive meningeal melanoma.
