The case of a rare, mature teratoma of the oculomotor nerve manifesting as an interpeduncular cistern mass is presented. A basilar tip aneurysm initially was suspected on the basis of lesion location and MR imaging appearance. Subsequent CT and catheter angiography studies were atypical for aneurysm, leading to surgical biopsy. Pathologic analysis revealed a well-circumscribed mass composed of mature representatives of all three major cell lines characteristic of mature teratoma. The imaging findings are described, and a brief literature review is provided.
本文报告一例罕见的动眼神经成熟畸胎瘤，表现为脚间池肿块。基于病变位置和磁共振成像表现，最初怀疑为基底动脉尖部动脉瘤。随后的计算机断层扫描和导管血管造影检查结果不典型，遂进行手术活检。病理分析显示，肿块边界清晰，由成熟畸胎瘤特征性的所有三种主要细胞系的成熟成分组成。文中描述了影像学表现，并提供了简要的文献综述。
