Isolated torsion of the Fallopian tube is an uncommon event. Surgery is often necessary to establish the diagnosis. This report focuses on a 15-year old female who presented with acute pelvic pain. Pelvic ultrasound showed an adnexal mass. The laparoscopy performed confirmed the diagnosis of isolated tubal torsion. Based on this experience as well as on other similar reported cases, characteristics of isolated torsion of the Fallopian tube are discussed. This pathology should be considered in the differential diagnosis of acute pelvic pain in the female patient. Prompt surgical intervention may allow for preservation of the tube.
