Extraaxial parasellar cavernous hemangioma.

Intracranial cavernous hemangiomas (cavernomas) are uncommon vascular hamartomas that develop infrequently in an extracerebrallocation, with the middle cranial fossa being the most frequently reported site [1, 2]. Accurate presurgical diagnosis is not often achieved, and because of their location and propensity to bleed profusely during surgery, these tumors are usually impossible to resect completely. We present a case of intracranial extracerebral cavernous hemangioma that illustrates the difficulty of differentiating this tumor diagnostically from other parasellar masses, in particular from meningioma. The MR, CT, and angiographic features of this lesion are described.
