Congenital Ovarian-Fallopian Tube Agenesis Predisposes to Premature Surgical Menopause: A Report of Two Cases

Background: Congenital agenesis of the Fallopian tube and ovary is a rare condition. Although several cases have been published on this condition, none have reported surgical menopause. We present two cases of congenital unilateral tubal and ovarian absence leading to surgical menopause. Case presentation: Case 1 underwent laparoscopic surgery for recurrent ovarian torsion and was found to have agenesis of the distal Fallopian tube and ovary. Case 2 underwent laparotomy for an adnexal mass and was found to have unilateral absence of the Fallopian tube and ovary with a contralateral large mucinous cystadenocarcinoma. Conclusion: Two cases of unilateral ovarian and partial tubal agenesis predisposed the patients to early menopause by requiring removal of the contralateral ovary due to recurrent torsion or ovarian cancer. Upon discovery of congenital absence of an ovary during surgery, an effort should be made to preserve the functionality of the contralateral adnexa and uterus if fertility is desired.
