Familial cerebral cavernous angiomas.
Three families with two or more members affected by cavernous angiomas of the brain are described and the other 17 reported in the literature are reviewed. The familial occurrence of cerebral cavernous angiomas has been considered a rare event; nevertheless, the experience of the authors (positive familiarity in three patients where two or more relatives have been explored radiologically) suggests that cavernous angiomas of the brain might be, at least in most cases, a familial disease. Therefore, when a patient with cerebral cavernous angioma is observed, a careful familial history and the exploration of the familial members by computerized tomography or better still by magnetic resonance must be performed. The high frequency of multiple lesions in familial cases, the surgical indications and the role of the ultrasonic prenatal diagnosis are also discussed.
