Isolated congenital segmental absence of fallopian tube is very rare. We report a case where partial absence of unilateral fallopian tube was incidentally diagnosed during cesarean delivery. It was not associated with any other abnormality in uterus, adnexa or genital system. Developmental mechanism could be torsion or vascular event, or a developmental defect in mullerian or mesonephric ducts.
Key words: Caesarean; fallopian tube; segmental; torsion.
