Metastatic choriocarcinoma with multiple neoplastic intracranial microaneurysms

Abstract

✓The authors report on a case of a metastatic choriocarcinoma that mimicked systemic necrotizing vasculitis on a cerebral angiogram. A 35-year-old woman presented with right hemiplegia and a drowsy mental state. A computed tomography (CT) scan revealed an intracerebral hemorrhage in the left frontal region. A cerebral angiogram showed multiple microaneurysms arising from the bilateral anterior cerebral arteries and middle cerebral arteries, and the renal angiogram showed multiple microaneurysms arising from the left distal renal artery. A chest CT scan revealed multiple metastatic lesions in the left lower lung field. The hematoma and microaneurysms were surgically removed. Choriocarcinoma was diagnosed after histological examination. Despite receiving postoperative chemotherapy, the patient died 1 month after the operation.
