Ruptured Tubal Pregnancy with a Negative Urine Pregnancy Test and Serum Beta Human Chorionic Gonadotropin

A rare case of ruptured tubal pregnancy with a negative urine pregnancy test (UPT)  and serum beta hCG was reported. The patient presented with massive intraperitoneal bleeding  and hypovolumic shock. Despite the negative UPT, a rupture tubal pregnancy was ruled out  and a consultation with the gynaecologist was not done. Exploratory laparotomy revealed  massive hemoperitoneum with a 5-cm purplish mass at the right fallopian tube and the right  salpingectomy was performed. The serum beta hCG was sent intraoperatively, and the result  was 4.2 mIU/mL. The pathological report confimed a tubal pregnancy containing a 0.5-cm  embryo and chorionic villi.
