We present a 38-year-old female with a giant dumbbell-shaped trigeminal neurinoma originating primarily in the middle cranial fossa, extending to the infratemporal and posterior fossae through the foramen ovale and Meckel's cave, respectively. Because of the large tumour extension into the Infratemporal Fossa, a combined skull base approach (zygomatic infratemporal - transmandibular) was utilised for tumour removal, with a subsequent excellent outcome. An extensive literature review since 1935, revealed 580 cases of surgically treated trigeminal neurinomas. Among these, only three were located in three distinct compartments, making this the rarest developmental pattern for trigeminal neurinomas.
我们报告了一名38岁女性，患有巨大哑铃形三叉神经鞘瘤，该肿瘤主要起源于中颅窝，分别通过卵圆孔和 Meckel 腔延伸至颞下窝和后颅窝。由于肿瘤广泛延伸至颞下窝，因此采用联合颅底入路（颧颞下 - 经下颌骨）切除肿瘤，术后效果良好。自1935年以来的广泛文献回顾显示，有580例接受手术治疗的三叉神经鞘瘤病例。其中，只有3例位于三个不同的腔室，这使其成为三叉神经鞘瘤最罕见的发育模式。
