Isolated Fallopian Tube Torsion with a Paratubal Cyst Treated with Laparoscopic Approach in the Third Trimester of Pregnancy: A Case Report and Literature Review

Abstract

A 29-year-old primigravid pregnant women was admitted to our tertiary center with complaints of abdominal pain, nausea, and vomiting at the 29 weeks of gestation. Ultrasonography revealed a 6 cm diameter cystic mass in the right adnexa, and there was a high suspicion of adnexal torsion. On magnetic resonance imaging, the right ovary appeared normal and there was a 6 cm cystic mass adjacent to the right ovary, and the findings supported isolated fallopian tube torsion. Emergency laparoscopy revealed that the right fallopian tube and para-tubal cyst were torsioned by 720°, and the fallopian tube was necrotic. This torsion did not include the ovary. Since the color tone of the fallopian tube did not recover after detorsion, the right salpingectomy was performed. After the patient was discharged, routine obstetric follow-ups were continued and 3375 g male infant was delivered by cesarean section at 39 weeks of gestation. ABSTRACT
