Abstract

The vast majority of pregnancies of unknown location (PUL) will be failing pregnancies and early intrauterine or ectopic pregnancies (EPs) that are too early to visualize on transvaginal scan. Very rarely, a positive pregnancy test in the presence of a negative scan will reflect an underlying human chorionic gonadotropin (hCG)-secreting tumor. We report a case in which elevated serum hCG led to the initial diagnosis of an EP which was subsequently found to be a placental site tumor of the ovary. This case shows that a misinterpretation of signs of EP can result in a delay in accurate diagnosis.
