MULTIPLE CEREBRAL PSEUDOANEURYSMS AND HEMORRHAGES - THE EXPANDING SPECTRUM OF METASTATIC CEREBRAL CHORIOCARCINOMA

Cerebral metastases occur in 10-20% of patients with choriocarcinoma. Although single oncotic and pseudoaneurysms have been reported, multip le pseudoaneurysms and hemorrhages are rare. A 33-year-old woman devel oped 10 intracerebral hemorrhages over a 30-day period. Angiogram show ed multiple focal areas of delayed contrast washout in distal vessels. Autopsy revealed intravascular choriocarcinoma without true aneurysm formation. A diagnosis of choriocarcinoma should be considered for wom en oi childbearing age presenting with cerebrovascular syndromes, espe cially those found to have cerebral aneurysm, pseudoaneurysm, and/or h emorrhage.
