Accessory fallopian tube: An extremely uncommon anomaly

Abstract

Accessory fallopian tube is an uncommon congenital and developmental anomaly of the mullerian duct [1]. The documented incidence among women seeking infertility treatment ranges between 6 and 10% [2]. A patient's accessory fallopian tube was discovered during a routine examination of the operative field, ovaries, and fallopian tube during a caesarean section. The accessory fallopian tube is a congenital anomaly that is connected to the ampullary portion of the primary fallopian tube. It is common for pyosalpinx, hydrosalpinx, cystic enlargement, and torsion to occur in the accessory fallopian tube, which can result in infertility and other complications. The ovum discharged by the ovary may also be captured by the accessory fallopian tube, resulting in infertility or ectopic pregnancy. During embryological development of the female urogenital system, the fallopian tube develops from the unfused cranial portion of the mullerian ducts. This duct is derived from embryonic mesoderm, the intermediate layer of germ cells. The accessory fallopian tube is produced by the bifurcation of the cranial end of the mullerian duct.
