Torsion Causing Interruption of the Ampullary Portion of the Fallopian Tube

Objective: To present a description of a young girl who presented acutely with symptoms and findings that are consistent with acute adnexal torsion, where resultant outcome would have led to perception of a congenital anomaly.

Design: Case report.

Setting: Tertiary pediatric hospital.

Patient(s): A young girl who presented acutely with symptoms consistent with adnexal torsion but who was found to have a torsion affecting a paratubal cyst and the midsegment of her fallopian tube.

Intervention(s): A salpingectomy was performed because of damage involving the ischemic paratubal cyst and tubal segment that left too little residual tube to allow for a future anastomosis of the residual unaffected components.

Main Outcome Measure(s): Operative findings, which give an explanation for midsegmental tubal absence.

Result(s): This case challenges previous reports that absent midsegment of a tube is a rare congenital anomaly.

Conclusion(s): Absent midsegment of a tube can be explained as an acquired anomaly, rather than proposing an unusual congenital anomaly.
