Familial occurrence of cavernous angiomata of the brain

A 27 year old man had attacks of violence for three years before he died in 1945. Necropsy revealed multiple cavernous angiomata of the brain. This man's daughter died in 1969 at the age of 28 years after a year of intermittent headaches. Necropsy showed a large cavernous angioma in the right temporal lobe. Until now the literature has contained only scanty circumstantial evidence for a familial occurrence of cavernous angiomata of the brain.
