Cavernous Angioma of the Cerebellopontine Angle

Although cavernous hemangiomas are commonly found supratentorially, their presence in the internal auditory canal is uncommon. We describe a case that was initially mistaken for a vestibular schwannoma due to its location in the cerebellopontine angle. Although there can be overlap in their presenta...

Description
Summary:Although cavernous hemangiomas are commonly found supratentorially, their presence in the internal auditory canal is uncommon. We describe a case that was initially mistaken for a vestibular schwannoma due to its location in the cerebellopontine angle. Although there can be overlap in their presentations, familiarity with the characteristic magnetic resonance imaging findings of both entities will aid in their differentiation and potentially affect preoperative planning.
