Cavernous angiomas are benign vascular malformations found within the CNS that may occur sporadically or in a familial pattern. Cavernous angiomas are also a complication of radiation therapy, especially in children. These angiomas can remain stable, enlarge over time, or bleed, and there are no factors that predict their occurrence or behavior.
Three genetic loci responsible for familial cavernous angioma (CCM1, CCM2, and CCM3) have been identified. Cavernomas are typically found supratentorially (approximately 80%), predominantly in the subcortical rolandic and temporal areas. Infratentorially, cavernous angiomas are most commonly found in the pons and cerebellar hemispheres (Sage and Blumbergs 2001). Originally thought to be relatively rare and most commonly detected during autopsy, the advent of MRI has led to an increased detection, with incidence rates now...
