Abstract

Neurilemmoma of the oculomotor nerve is rare and infrequently presents as an orbital mass. We report a neurilemmoma arising from the cavernous sinus with its major part extending into the orbit. The Antoni A part of the neurilemmoma showed intermediate signal intensity in both T1- and T2-weighted MR images and exhibited postcontrast enhancement. The Antoni B part revealed hypointensity on T1-weighted images, hyperintensity in T2-weighted images, and showed no contrast enhancement.

摘要

动眼神经神经鞘瘤罕见，很少表现为眼眶肿物。我们报告1例起源于海绵窦、大部分延伸至眼眶的神经鞘瘤。该神经鞘瘤的Antoni A区在T1加权和T2加权磁共振图像上均呈中等信号强度，增强扫描有强化。Antoni B区在T1加权图像上呈低信号，T2加权图像上呈高信号，增强扫描无强化。
