Twisted Fimbrial Cyst (Paraovarian Cyst): A Rare Cause of Acute Abdomen

We present a case of a 22-year-old female who presented with acute abdomen and amenorrhea. Emergency laprotomy was done with a clinical diagnosis of ectopic pregnancy. On laprotomy, twisted fimbrial cysts were found. Thus, although fimbrial cysts are rarely twisted, they should be considered as a cause of acute abdomen in a female of reproductive age group.
