Hemangioma calcificans--a benign epileptogenic lesion.

Hemangioma calcificans is a rare condition that may be regarded as a calcified cerebral cavernous angioma. The clinical presentation is usually that of epilepsy in an adult. A calcified nodule is visible on radiographs of the skull or computed tomographic (CT) scans. Angiography does not demonstrate vascularity. It is usually a solitary subcortical lesion that is surgically removable. Because of the favorable results from treatment of this lesion, this report reviews the clinical and radiological features described in the literature and includes an additional case.
