A 13-year-old girl visited a clinic because of left lower abdominal pain and frequent vomiting. She was suspected of having ovarian torsion because computed tomography (CT) showed a cystic lesion in the pelvic cavity; thus, she was referred to our hospital. Both ultrasound and CT showed a multicystic lesion 10 cm in diameter without a solid component in the left lower abdominal space above the bladder. The cystic components had no nouveau formation signs. She underwent emergent laparotomy under suspicion of ovarian torsion. The intraoperative findings were a cystic mass protruding from the surface of the left fallopian tube, which had been twisted 360° counterclockwise. We diagnosed this cystic mass as a paratubal cyst and performed cyst enucleation after confirming no injury to the blood supply of the left ovary. The postoperative course was uneventful. She was discharged from the hospital one week after surgery. Paratubal cyst is a rare disease. We herein report a case of tubal torsion due to a paratubal cyst initially suspected of being ovarian torsion and accurately diagnosed during surgery.
