This is related to a case suggestion I got from "CodeDog." Thanks!
A 40 year old woman 12 weeks postpartum presents with irregular vaginal bleeding. Physical examination shows an enlarged uterus. A beta-hCG level is elevated. Imaging shows bilateral ovarian cysts as well as hypervascular heterogeneous mass in the uterus with areas of necrosis and hemorrhage.
Challenge: This is a tough one, what's your impression?
