The surgical resection of the pontomesencephalic junction (PMJ) glioma is difficult because the access is challenging due to nearby complicated neurovascular structures.
We report a left ventrolateral PMJ glioma successfully resected via the oculomotor-tentorial triangle (OTT), with improved right extremity weakness postoperatively while preserving the pyramidal tract, which resided laterally and posteriorly to the lesion.
This case demonstrates the value of the OTT in brainstem surgery.
脑桥中脑交界处（PMJ）胶质瘤的手术切除困难，因为由于附近复杂的神经血管结构，手术入路具有挑战性。
我们报告一例通过动眼神经-小脑幕三角（OTT）成功切除的左侧腹外侧PMJ胶质瘤，术后右侧肢体无力改善，同时保留了位于病变外侧和后方的锥体束。
该病例证明了OTT在脑干手术中的价值。
