Abstract

Background Choriocarcinoma coexisting with or after normal pregnancy is extremely rare. To our knowledge, our case report is the first time cerebral mycotic pseudoaneurysms from choriocarcinoma have been proven angiographically. Case Description A 38-week pregnant 26-year-old woman presented with an acute left frontal hemorrhage. She underwent emergency cesarean section, followed by hematoma evacuation and resection of what grossly appeared to be a medium-sized arteriovenous malformation at the time of surgery. Angiogram before and after resection showed no obvious vascular pathology. One month later, she returned with status epilepticus, and an acute parenchymal hematoma posterior to the surgical resection cavity was identified. Angiography showed a multilobulated pseudoaneurysm along the left middle cerebral artery. This was resected and found on histopathology to have choriocarcinoma within and around the blood vessels. Serum human chorionic gonadotrophin levels increased daily. Pan computed tomography showed a left lung lobular mass. The diagnosis was stage 4 World Health Organization score 9 high-risk metastatic choriocarcinoma requiring radiation followed by multiagent chemotherapy. Two weeks later, she had another seizure. An angiogram showed an unruptured pseudoaneurysm along the right posterior cerebral artery, which was embolized. Conclusions Metastatic choriocarcinoma is rarely considered during a viable pregnancy but is almost always fatal if unrecognized. Early recognition enhances the chances of cure with chemotherapy. Arteriovenous malformations are typically considered in young women with intracerebral hemorrhages and have higher risk of rupture in pregnant women, but physicians should also be aware of metastatic choriocarcinoma and the development of mycotic aneurysms in peripartum women with intracerebral hemorrhages.
