We experienced an unreported rare case with an adnexal mass causing severe acute abdomen during pregnancy. A 30-year-old Japanese pregnant woman was transported to our hospital for her right lower abdominal pain at 30 weeks of gestation. Magnetic resonance imaging and ultrasound demonstrated a cyst measuring 3–4 cm in diameter adjacent to the right ovary, and a parovarian cyst was considered to be the most probable diagnosis. We strongly suspected torsion of the ovarian pedicle or fallopian tube in conjunction with her clinical symptoms. Laparotomy revealed that the elongated right fallopian tube accompanied by a paratubal cyst was coiling tightly 2.5 times round the right ovary, causing apparent congestion and enlargement of the right ovary. Soon after we released the congested right ovary from the coiling of the fallopian tube, the congestion subsided. The postoperative course was favorable, and pregnancy and delivery were uneventful.
