| Discussion | Cavernous sinus hemangioma is an uncommon cause of a cavernous sinus mass. Preoperative diagnosis is important to avoid unexpected surgical blood loss. * MRI finding The key features that are helpful in making the diagnosis are a 'soft' appearing mass centered on the cavernous sinus, with pronounced T2 hyperintensity and contrast enhancement. T1: hypointense to brain T2: markedly high signal intensity CE T1: vivid homogeneous enhancement, gradual filling in on dynamic sequences (similar to cavernous hemangiomas elsewhere) |
