title: Ureteral endometriosis and ovarian mucinous cystadenoma presenting with acute pyonephrosis.
abstract: BACKGROUND
  Endometriosis is a common disease, but ureteral involvement is rare. Nonspecific clinical presentations of ureteral endometriosis may result in diagnostic difficulty.
  
  
  OBJECTIVE
  To discuss the diagnosis and management of such a case.
  
  
  METHODS
  To report a case of ureteral involvement with endometriosis and review the literature.
  
  
  RESULTS
  The case presented with right lower quadrant pain giving rise to initial diagnostic possibility of acute appendicitis. Subsequent evaluation revealed the diagnosis of right pyonephrosis due to midureteral endometriosis with right ovarian mucinous cystadenoma.
  
  
  CONCLUSIONS
  The diagnosis of ureteral endometriosis requires a high index of clinical suspicion. The importance of ultrasound in the evaluation of acute abdomen in women can not be overemphasised.
