title: Hemangioma calcificans.
abstract: Two cases of intraparenchymal hemangioma calcificans, an extremely rare variety of cavernous angioma, are reported. These lesions, well demonstrated on roentgenographic films of the skull and on computerized tomography scans, appeared avascular during the course of cerebral angiography. Clinical features, as well as macroscopic and microscopic evaluation, are discussed. The differential diagnosis from other intracranial calcified lesions is difficult. The literature describing this rare lesion is briefly reviewed, with special regard to the surgical indications.
