Abstract
A 38-year-old woman was seen at our hospital because of right lower quadrant abdominal pain in January 2007. Oral analgesic did not relieve the symptom and she was admitted to our hospital two days later when marked leukocytosis of 10,930 cells/mm3 and C-reactive protein of 5.9 mg/dl were noted. We conducted emergency surgery with a diagnosis of acute appendicitis with an ovarian cyst determined by computed tomography (CT). Intraoperative exploration revealed a normal appendix and a cyst 60 mm in longer diameter which was continuous to the uterine tube and adjacent to the right ovary. The cyst was twisted counter-clockwise by 540 degree. The diagnosis of torsion of hydrosalpinx was made.
Torsion of hydrosalpinx is rare and is often misdiagnosed as torsion of an ovarian cyst, but torsion of hydrosalpinx should be considered in female patients with lower abdominal pain after tubal sterilization.
