Hereditary hemorrhagic telangiectasia. A case report with known cerebral involvement and cardiac catheterization data.

Numerous bleeding episodes, neurological signs and symptoms, and pulmonary arteriovenous malformations are well documented in reports of families with hereditary hemorrhagic telangiectasia. It is always assumed that these are due to the arteriovenous malformations. We are here reporting a case with positive cerebral angiographic findings of large arteriovenous communications, as well as catheterization data revealing pulmonary abnormalities secondary to the cerebral arteriovenous fistula, but no abnormalities within the pulmonary vasculature itself.
