A rare incidental case of an accessory fallopian tube

Abstract

Developmental anomalies of the mullerian duct system represent one of the most fascinating disorders that obstetricians and gynecologists encounter as the mullerian ducts are the primordial anlage of the female reproductive tract. Accessory fallopian tube is one such rare anatomical mullerian duct error that has been occasionally reported in the literature. Due to the limited data available and lack of awareness about this entity, it is often overlooked. This report describes one such rare incidental case of an accessory fallopian tube in a 35-year-old female who was diagnosed with right ruptured tubal pregnancy. The patient was about six weeks pregnant and presented with a severe lower abdominal pain. Transvaginal sonography showed that the right fallopian tube contained a gestational sac with a yolk sac and her urine pregnancy test was positive, so a diagnosis of a right ruptured tubal pregnancy was made. Laparotomy and right salpingectomy were performed. Histopathological examination revealed right ruptured tubal pregnancy with a coexisting accessory fallopian tube. In conclusion, an early identification and prompt intervention are paramount for treating such an anomaly as it can have many gynecological detrimental implications.
