Ganglioneuromas are rare tumors arising from retroperitoneal and posterior mediastinal sympathetic nerves. Intracranial trigeminal nerve ganglioneuromas are even more rare, with only seven cases reported to date. We present a case of a 65-year-old male with a right-sided throbbing headache type and blindness in his right eye. Magnetic resonance imaging revealed an ill-defined mass lesion in the middle-cranial fossa, with a few areas having a reduced apparent diffusion coefficient and multiple microhemorrhages. Piecemeal debulking of the tumor was achieved by performing a right-middle craniotomy via the pterionic and sub-temporal approach. The detected histological features matched those of a ganglioneuroma (maturing type) of the trigeminal nerve.
神经节细胞瘤是起源于腹膜后和后纵隔交感神经的罕见肿瘤。颅内三叉神经节细胞瘤更为罕见，迄今为止仅报道过7例。我们报告一例65岁男性患者，其患有右侧搏动性头痛并右眼失明。磁共振成像显示中颅窝有一个边界不清的肿块病变，部分区域表观扩散系数降低且有多处微出血。通过经翼点和颞下入路进行右侧中颅窝开颅手术，实现了肿瘤的分块切除。检测到的组织学特征与三叉神经节细胞瘤（成熟型）相符。
