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.

Vsual delight... The rarity of cavernous hemangioma in a cavernous sinus does make it a visual delight.
But a verbal agony!

Sir , What is the reason for hyperintensity in 1st image ?? Isn't it T1 weighted image ??
