UNASSIGNED: Background: A 32-year-old @entity1 with @entity249 due to bilateral laparoscopic salpingectomy conceived twins with @entity52 ( @entity52 ). She developed moderate @entity43 which was treated with anticoagulant therapy. The subsequent course of the twin pregnancy was normal until the 17th week of gestation when she presented to hospital because of a sharp @entity158 in the right lower abdomen which ceased after admission. Case: Except for a single incident of @entity391 , @entity1 had no other subjective symptoms. The clinical examination showed tenderness of the lower right abdominal segment on palpation. The surgeon and the urologist found no signs of an acute surgical or urologic condition, and laboratory findings were within normal reference ranges for pregnant @entity1 . Two days after admission the @entity158 reappeared; it was now much stronger and colic-like. The @entity158 was initially located supraumbilically but subsequently spread diffusely across the lower abdomen. Abdominal guarding was present and laboratory findings showed an increase in inflammatory parameters. An enlarged and @entity4 was found on transvaginal ultrasound. Conclusion: Exploratory laparotomy via a vertical midline abdominal transection revealed a torqued necrotic right ovary with elements of @entity32 and inflammatory adhesions involving the entire pelvis. The @entity1 underwent right-sided ovariectomy and adhesiolysis. Recovered was normal and the @entity1 was delivered of healthy twins in the 37th week of gestation.
