Familial vascular malformations. Report of 25 members of one family.

چکیده
Vascular malformations are described in 25 members of one affected family. Most of these lesions were cavernous hemangiomas, but arteriovenous malformations and capillary hemangiomas were also microscopically observed in some specimens. The five generation pedigree suggests the vascular malformations are genetically determined on the basis of a dominant inherited trait.

متن کاملValue of gradient-echo magnetic resonance imaging in the diagnosis of familial cerebral cavernous malformation.
BACKGROUND Cerebral cavernous malformations (CCMs) are congenital vascular anomalies that can cause seizures, intracranial hemorrhages, focal neurological deficits, and migrainelike headaches.
