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.
