【讨论问题】如何诊断

【讨论】

评论:右侧小脑半球见一卵圆形以长T1、长T2信号为主的混杂信号,其内信号欠均匀,边界清楚, DWI呈低信号,增强扫描呈显著欠均匀强化,邻近四脑室受压。右侧小脑囊实性肿瘤占位病变,考虑:1.血管母细胞瘤;2.髓母细胞瘤不能除外
 
【病理结果】小脑神经鞘瘤
 
【病例小结】

颅内神经鞘瘤约占颅内原发肿瘤的8%,一般起源于颅神经主干的雪旺氏细胞,多为良性,并有可能并发神经纤维瘤。非源于神经的主干的神经鞘瘤极少见,仅占神经鞘瘤的1%。此肿瘤好发于儿童和年轻人,无明显性别差异。其大体病理多为含有壁结节的囊实性肿块,囊内为深绿色囊液。
影像学表现1.肿瘤好发于大脑半球及小脑半球的较表浅部位,占位征象较明显,瘤周有水肿;发生于脑室旁者约20%,多见于第四脑室,脑室受压变形,瘤周水肿不明显,肿瘤也可见于脑干与鞍上池。钙化较颅神经主干的鞘瘤多见。

2.平扫病灶实性部分多为等密度,囊性部分为低密度;T1WI大多数呈等、低信号, T2WI为不均匀高信号;在DWI上实性部分等信号,囊性部分呈低信号。
3.增强扫描肿瘤实性部分强化明显,边界清楚。
