Abstract

Choriocarcinoma is a rapidly growing tumor that characteristically outgrows its blood supply. We report a rare case of metastatic choriocarcinoma presenting with acute right flank pain due to kidney rupture secondary to renal metastasis. The renal metastasis was embolised to stanch blood for control of hemorrhage. A brief review of the imaging features and therapeutic options for the ruptured renal metastases is discussed along with the case.
