We report an extraordinarily rare case of a pregnant patient with history of multiple ovarian cyst surgery. The corpus luteum developed on an ectopic ovarian tissue, miming an tubal pregnancy. One week later after the diagnostic laparoscopy an intrauterine pregnancy was visualised. Therefore, ectopic ovarian tissue with normal follicular activity may appear after multiple ovarian surgery.
Keywords: corpus luteum; ectopic ovarian tissue; ectopic pregnancy; ovarian surgery; tubal pregnancy.
