OBJECTIVE: Four types of cavernous malformations (Types I-IV) have been described on the basis of their magnetic resonance imaging (MRI) appearance. The nature of the Type IV cavernous malformation is unclear. It has been suggested that these small lesions, which are well observed only on gradient echo MRI scans, are capillary telangiectasias. We sought to understand the relationship of Type IV cavernous malformations to the other cavernous malformation subtypes.
