title: Uterine cervical diverticulum resembling a degenerated leiomyoma.
abstract: BACKGROUND
  Uterine diverticulum is a very rare anomaly. Most previously reported cases were called "pregnancy-associated sacculations," and only 2 cases were considered true uterine diverticula.
  
  
  METHODS
  A 41-year-old woman presented with fever and lower abdominal pain. An extrauterine mass was detected, and a hysterectomy was performed. Pathological examination revealed a cystic uterine diverticulum lined with cervical glands and myometrium arising from the cervix. The final diagnosis was an infected uterine cervical diverticulum.
  
  
  CONCLUSIONS
  Cervical diverticulum is a rare lesion that should be added to the differential diagnosis of a woman presenting with a pelvic mass.
