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.
我们展示了一例罕见的海绵窦原发性脑膜黑素细胞瘤的CT、磁共振血管造影及组织学表现。主要鉴别诊断在于含黑色素的肿瘤与轴外海绵状血管瘤之间。放射学成像无法区分侵袭性较低的原发性脑膜黑素细胞瘤与侵袭性较高的脑膜黑色素瘤。
