Isolated Torsion of Bilateral Fallopian Tubes Combined with Tubal Endometriosis: a Case Report

Torsion of the fallopian tube is less frequent. Indeed, isolated bilateral fallopian tube torsion is rare and often diffi cult to diagnose. The etiology of fallopian tube torsion is still uncertain, especially when this is not associated with torsion of the ovary. We present a case of the torsion of isolated bilateral fallopian tube combined with tubal endometriosis. A 30-year-old woman presented with chronic abdominal pain of 5-month duration and severe dysmenorrhea. Presumptive diagnosis by ultrasound and magnetic resonance imaging was both adnexal endometriosis. At laparoscopy, the fi mbrial ends of both tubes were dilated, twisted and necrotic changes with adhesion to omentum, which subsequently led to terminal obstruction of that tube. However, both ovaries and uterus were normal. Laparoscopic bilateral salpingectomy was performed. The postoperative histological report confi rmed hematosalpinx with tubal endometriosis. To our knowledge, this is the fi rst case of isolated and bilateral fallopian tubes torsion combined with tubal endometriosis.
