[Venous angiomas of the brain. Diagnosed by CT and angiography (author's transl)]

Report on three cases of the relatively rare venous angioma of the brain presenting a classical angiographic pattern. On CT, one could not be demonstrated; the other two were detected because they showed a linear hyperdensity after contrast enhancement. Gross and microscopic pathology are described of one of these cases in a patient who died of an endocrine crisis following a sudden hemorrhage into a coexisting tumor of the pituitary gland. Only angiography provides a specific diagnosis; CT alone may only be able to suggest the presence of a vascular malformation. The angiographic, CT- and clinical findings and their value are discussed.
