Unusual locations for cavernous hemangiomas: report of two cases and review of the literature.

Abstract

Cavernous hemangiomas are most commonly found within the subcortical neural parenchyma near the fissura Rolandi, in the basal ganglia, or in the brain stem. Because of advancing neuro-imaging technology and thus resulting in a higher incidence of cavernous hemangiomas they have rising impact in neurosurgery. We present two unusual cases of extra-axial cavernous hemangiomas: one located at the frontal falx, the other within the bone of the right frontal bone. We discuss these and other cases in the literature with respect to the more common differential diagnoses and the appropriate therapy regimen for cavernous hemangiomas in these locations.
