Familial Occurrence of Intracerebral Cavernous Angioma: A case report

I．はじめに

　脳内海綿状血管腫は比較的稀な疾患と考えられていたが，CT scanにて診断可能なことからその報告例も徐々に増加し^2,7,16）必ずしも稀な疾患とは考えられなくなった．しかし，その家族内発生については数例の報告を見るにすぎない^{4,5,9,12,14,18）}．

　今回われわれは，親子に発生した脳内海綿状血管腫の症例を経験したので呈示し，文献的考察を加え報告する．

A case of familial occurrence of intracerebral cavernous angioma is reported. The patients were a mother and her eldest son, a 48-year-old womenand a 28-year-old men, respectively. The mother, a hypovascular mass in the right frontal lobe was excised surgically, and in the son a well demarcated mass in the left temporal lobe was extirpated. Pathological examination in each case revealed cavernous angioma.

Familial occurrence of intracerebral carvernous angioma is extremely rare.
