[Familial cerebral aneurysms in three families, with two sibling pairs]
The authors describe two pairs of siblings and a mother-son with cerebral aneurysms and the characteristics of familial intracranial aneurysms are briefly discussed. Family 1: A 54-year-old hypertensive woman (case 1) developed subarachnoid hemorrhage and a saccular aneurysm at the proximal portion of the left anterior cerebral artery was demonstrated on the angiogram. An azygos anterior cerebral artery was found as an associated anomaly. A 53-year-old hypertensive woman (case 2), a younger sister of case 1, suffered from subarachnoid hemorrhage and a saccular aneurysm at the distal portion of the right anterior cerebral artery was found on the angiogram. Vertebral angiogram showed bilateral fenestration of the extracranial vertebral arteries as a coincidental anomalies. Neck clipping for the aneurysms were successfully done in these two cases. Family 2: A 52-year-old hypertensive woman (case 3) suffered from subarachnoid hemorrhage and vertebral angiogram demonstrated a saccular aneurysm at the distal portion of the right posterior inferior cerebellar artery. The aneurysm was re-bled before surgical intervention and she died five days after admission. A 65-year-old hypertensive woman (case 4), an elder sister of case 3, was admitted with subarachnoid hemorrhage. Vertebral angiogram showed a saccular aneurysm on the proximal portion of the left posterior inferior cerebellar artery at the junction of the vertebral artery and a massive extravasation of the contrast medium from the aneurysm. The patient died three days after the onset before surgical intervention.(ABSTRACT TRUNCATED AT 250 WORDS)
