Intracranial cavernous angioma. Report of two cases in the same family.

We report two cases of intracranial cavernous angioma in members of one family and discuss our clinical and surgical findings in a further 10 cases of this lesion seen in the past five years. We stress the value of RNM, which supplies a precise diagnosis of nature, site and size, especially when the lesion is surrounded by a recent hematoma. NMR is especially indicated in suspected familial cavernous angioma, as in the cases reported.
