Schwannomas are benign encapsulated tumors arising from the sheaths of peripheral nerves. They present as slowly enlarging solitary lumps, which may cause neurological defects. Multiple schwannomas in non-neurofi bromatosis type 2 patients are extremely rare. We report a case of a 60-year-old female patient, without any family history of neurofibromatosis or schwannomatosis, presented with trigeminal neuralgia and progressive facial nerve palsy. Magnetic resonance imaging revealed the presence of acoustic schwannoma involving facial nerve and trigeminal schwannoma of the cisternal part of the nerve involving gasserian ganglion (Meckel’s cave). After gamma knife radiosurgery, trigeminal neuralgia was relieved completely with improvement of facial nerve palsy.
施万细胞瘤是起源于周围神经鞘膜的良性包膜肿瘤。它们表现为缓慢增大的孤立肿块，可能导致神经功能缺损。在非2型神经纤维瘤病患者中，多发性施万细胞瘤极为罕见。我们报告一例60岁女性患者，无神经纤维瘤病或施万细胞瘤病家族史，表现为三叉神经痛和进行性面神经麻痹。磁共振成像显示存在累及面神经的听神经瘤和累及半月神经节（梅克尔腔）的神经脑池段三叉神经瘤。伽玛刀放射外科治疗后，三叉神经痛完全缓解，面神经麻痹有所改善。
