Adnexal torsion accounts for 2.7% of all gynecological emergencies, but isolated torsion of fallopian tube is an infrequent yet significant cause of lower abdominal pain in women, which generally presents in the reproductive age group. The overall incidence is 1 in 1.5 million women and is generally isolated and unilateral.1 Patients typically present with intermittent pain related to torsion and detorsion of the involved adnexa. Early diagnosis and treatment is necessary if a twisted tube or part of it is to be preserved; early laparoscopy may be a considerable diagnostic tool in these cases. We report a case of isolated torsion of fallopian tube containing an ectopic pregnancy.
