title: Gallstones presenting as a cul-de-sac mass.
abstract: BACKGROUND
  Pelvic masses requiring surgical evaluation have many different causes.
  
  
  METHODS
  In an unusual case, a pelvic mass was found to comprise approximately 40 gallstones. Laparoscopy was performed, and the gallstones were removed easily.
  
  
  CONCLUSIONS
  Nongynecologic causes should be considered in the differential diagnosis of pelvic masses.
