[Adnexal torsion and concominant appendicitis during third trimester of pregnancy--a case report].

Adnexial torsion is a rare, but important cause for abdominal pain during pregnancy. During pregnancy, its frequency is 10-20%, with highest frequency in the first trimester. We present a case of 24 year primigravida, with an acute onset of clinical symptoms with concominant disease chronic pyelonephritis. The initial diagnosis was exacerbation of the concominant disease and acute inflammation of the appendix. The intraoperative diagnosis was right adnexial torsion and inflammation of the appendix; the diagnosis was pathologically proved. Although rare, it can be included in the differential diagnosis of acute abdomen during pregnancy.
