Abstract
The screening of asymptomatic individuals in families with intracranial aneurysms has been advocated to detect unruptured aneurysms before a major hemorrhage occurs. We report a 39-year-old male member of a large Dutch family, with a documented history of intracranial aneurysms, who suffered a subarachnoid hemorrhage 2 years after cerebral digital subtraction angiography using intravenously administered contrast medium showed no abnormalities. Conventional arteriography demonstrated three intracranial aneurysms measuring 3 x 3 mm. Potential alternative screening procedures are discussed.
