Familial hypertensive intracerebral hemorrhage and autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is a generalized disease known to be associated with intracranial aneurysms. Non-aneurysmal intracerebral hemorrhage (ICH) has also been reported in ADPKD. We report a familial clustering of ICH and symptomatic ADPKD. This pedigree had at least six affected family members who suffered from ADPKD, hypertension and non-aneurysmal ICH. The proband demonstrated ADPKD, hypertension and cerebral hemorrhage. To our knowledge, this is the first report of familial ICH in ADPKD, which may have underlying genetic and environmental etiologies.
