FD American Society of Neuroradiology SP 1087 OP 1090 VO 17 IS 6 A1 S H Faro A1 R A Koenigsberg A1 A R Turtz A1 S E Croul YR 1996 UL http://www.ajnr.org/content/17/6/1087.abstract AB 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.
