Trochlear nerve schwannoma is extremely rare, with only 35 pathologically confirmed patients being reported in the literature. Here, the authors report a patient of trochlear nerve schwannoma in the prepontine cistern manifesting as facial pain and double vision and presenting the image characteristics of repeated intratumoral hemorrhage, which has never been reported in the literature. Total tumor along with a portion of the trochlear nerve was removed by using a retrosigmoid approach. Facial pain disappeared after operation, and the diplopia remained. Follow-up studies have shown no tumor recurrence for 2 years and the simultaneous alleviation of diplopia. Information regarding the clinical presentation, radiological features and surgical outcomes of trochlear nerve schwannoma are discussed and reviewed in the paper.
滑车神经鞘瘤极为罕见，文献中仅报道了35例经病理证实的患者。在此，作者报告1例桥前池滑车神经鞘瘤患者，表现为面部疼痛和复视，具有肿瘤内反复出血的影像学特征，这在文献中尚未见报道。采用乙状窦后入路切除了整个肿瘤及部分滑车神经。术后面部疼痛消失，但复视仍存在。随访研究显示，2年来无肿瘤复发，复视同时有所减轻。本文对滑车神经鞘瘤的临床表现、影像学特征及手术结果进行了讨论和综述。
