title: Large mesonephric cyst with acute adnexal torsion in a teenage girl.
abstract: BACKGROUND
  Mesonephric duct remnants usually do not present any clinical dilemma. However, if the cellular lining remains active, it may lead to cystic lesions that may cause pain or torsion of the adnexa.
  
  
  METHODS
  This is a 13-year-old female who presented because of severe pelvic pain. Ultrasound and CT scan revealed a large cystic mass in the pelvis. Mini-laparotomy confirmed torsion of the left adnexa due to the mass. The adnexa was untwisted. The cyst and the left tube were removed and the ovary regained its blood flow and was saved.
  
  
  CONCLUSIONS
  Mesonephric duct cyst should be considered in the diagnosis of pelvic masses in adolescent girls.
