Unilateral congenital ovarian and partial tubal absence: report of four cases with review of the literature.

Objective: To present four rare cases of congenital unilateral tubal and ovarian abnormalities with their laparoscopic images.

Design: Case report.

Setting: Baskent University Faculty of Medicine, Department of Obstetrics and Gynecology, Konya, Turkey.

Patient(s): Three patients with infertility showing abnormality on hysterosalpingography and a fourth patient with acute pelvic pain who were admitted to our clinic.

Intervention(s): All four patients underwent laparoscopic surgery.

Main Outcome Measure(s): Case 1 showed an absence of a distal tubal segment with ipsilateral ovarian agenesis. Case 2 showed a unilateral partial distal tubal absence with normal adjacent ovary. Case 3 showed a twisted and adherent tube with ipsilateral ovarian absence. Case 4 showed a unilateral ovarian agenesis and contralateral acute adnexal torsion.

Result(s): We detected four cases of unilateral ovarian and partial tubal absence in these operations.

Conclusion(s): We present four unusual cases of unilateral ovarian and partial tubal absence. The absence of one ovary and tube may be explained by two possible etiopathogenic causes: asymptomatic adnexial torsion or congenital malformation.
