Abstract

A 65-year-old woman had been conservatively treated as idiopathic trigeminal neuralgia for over 25 years, because conventional computed tomography (CT) and magnetic resonance imaging(MRI) showed no abnormality in the cerebello-pontine(CP) angle cistern. She received a detailed MRI by constructive interference in steady state and diffusion weighted image(DWI) sequences. Those sequences on MRI well demonstrated a epidermoid tumor in the CP angle cistern, and the removal of the tumor completely resolved the neuralgia. Since a small epidermoid in the CP angle cistern seems to be unrecognized by conventional CT and MRI, detailed evaluation by DWI sequence, which has been widespread recently, is required for patients with trigeminal neuralgia.

摘要

一名65岁女性因特发性三叉神经痛接受保守治疗超过25年，因为传统计算机断层扫描（CT）和磁共振成像（MRI）显示脑桥小脑（CP）角池无异常。她接受了稳态构成干扰和扩散加权成像（DWI）序列的详细MRI检查。MRI上的这些序列很好地显示了CP角池内的表皮样囊肿，肿瘤切除后神经痛完全缓解。由于CP角池内的小表皮样囊肿似乎无法被传统CT和MRI识别，对于三叉神经痛患者，需要通过最近广泛应用的DWI序列进行详细评估。
