Two Cases of Early Rebleeding after Total Removal of Hematoma due to Metastatic Choriocarcinoma

ABSTRACT

Among metastatic brain tumors, choriocarcinoma has a highly malignant nature and because of the vascular invasion of trophoblastic cells,tends to hemorrhage. Surgery is recommended for patients with a single cerebral metastasis, or for those who fail to respond to chemotherapy. We encountered two unusual cases in which early rebleeding occurred after the total removal of a hematoma arising from metastatic choriocarcinoma, and confirmed by post-operative tissue biopsy.
