Cavernous Haemangioma of Cavernous Sinus-MRI

Cavernous hemangiomas occur very rarely in the cavernous sinus and are difficult to diagnose preoperatively.  MR images showed hypointensity on T1-weighted images and well-defined hyperintensity on T2-weighted images with marked homogeneous enhancement after contrast material administration.  Extraaxial cavernous hemangiomas are rare and very rarely arise in the cavernous sinus . Diagnostically differentiating hemangiomas from tumors such as meningiomas or schwannomas at this site is often difficult.
