Isolated Fallopian Tube Torsion Presenting as Acute Abdomen

: A Case Report

Abstract

Adnexal torsion is relatively common, but isolated torsion of the fallopian tube is rare. We report herein on a case of isolated torsion of the fallopian tube causing acute pelvic pain. A 30-year-old woman was admitted to our emergency department with a chief complaint of right lower abdominal pain. Vaginal ultrasound, enhanced computed tomography, and magnetic resonance imaging showed bilateral adnexal masses and normal ovaries. Two days of conservative management did not improve her condition. We therefore gave her an emergency probe laparotomy. The laparotomy confirmed the diagnosis of isolated torsion of the right fallopian tube. We performed a right tubectomy, left salpingostomy, and bilateral surgical adhesiolysis. The histological specimens revealed a hemosalpinx with necrosis. The patient's postoperative course was satisfactory. Isolated torsion of the fallopian tube is an uncommon event. However, prompt surgical intervention may allow for preservation of the tube. Familiarity with this uncommon clinicopathologic entity will help clinicians evaluate the differential diagnosis of acute lower abdominal/pelvic pain in female patients.
