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. An urgent laparotomy was done, which however showed a twisted para-ovarian cyst with a twisted fallopian tube on the left side. The para-ovarian cyst was removed along with left sided fallopian tube and the patient made an uneventful recovery. Torsion of a para-ovarian cyst and fallopian tube is rare, but it should be considered in the differential diagnosis of acute abdomen in women who are in the reproductive age group.
