Management of incidental cavernous malformations: a review.

Cavernous malformations (CMs) are angiographically occult vascular malformations that are frequently found incidentally on MR imaging. Despite this benign presentation, these lesions could cause symptomatic intracranial hemorrhage, seizures, and focal neurological deficits. Cavernomas can be managed conservatively with neuroimaging studies, surgically with lesion removal, or with radiosurgery. Considering recent studies examining the CM's natural history, imaging techniques, and possible therapeutic interventions, the authors provide a concise review of the literature and discuss the optimal management of incidental CMs.
