Torsion of the fallopian tube.

Although an infrequent cause of acute lower abdominal pain, fallopian tube torsion should be considered whenever a woman presents with this complaint. Early diagnosis and surgical intervention may save a tube that has not yet infarcted, yet initial presentation may give little indication of the seriousness of the condition until peritonitis develops. Definitive treatment is removal of the affected adnexa. Diminished fertility and an increased incidence of ectopic pregnancy in the remaining fallopian tube follows unilateral salpingectomy. A case history of fallopian tube torsion is presented.
