| 摘 要： | 颅内脑外型海绵状血管瘤好发于中颅窝海绵窦区,典型病例磁共振表现为T1WI呈等或低信号,T2WI呈明显高信号,增强扫描明显强化,本文报道了1例不典型三叉神经海绵状血管瘤,磁共振成像下等及稍长T2信号、灶内点状短T1信号及增强扫描不强化是其不典型征象。

| Abstract: | Extracerebral cavernous hemangioma typically occurs in cavernous sinus in middle cranial fossa,showing iso-or hypointensity on T1WI,obvious hyperintensity on T2WI,and evident enhancement after contrast administration during magnetic resonance imaging(MRI).In this article we report one case of atypical cavernous hemangioma of the trigeminal nerve,with atypical MRI findings including isotense or slight long T2 signal,dotty short T1 signal,and non-enhancement on T1WI. |
