Torsion- of para-ovarian cyst resulting in secondary torsion of the fallopian tube: a cause of acute abdomen.

A 32-year-old woman presented with abdominal pain in the left lower quadrant, of one day's duration. Ultrasonography of the abdomen revealed a cystic structure in the right adnexa, probably with torsion. Computerized tomography of abdomen and pelvis showed a large pelvic cyst which arose most likely from the left ovary.
