An unusual case of cervical diverticulum identified by presence of 3 cavities at diagnostic hysteroscopy.

Herein is presented the case report of a patient who had severe dysmenorrhea since menarche, known right unicornuate uterus with a left rudimentary horn, and recurrent hematometra. Previous hysteroscopic drainage of the hematometra temporarily alleviated the symptoms. At subsequent hysteroscopy, 3 cavities were identified, 2 corresponding to the uterine horns and the other to a cervical diverticulum. Hysteroscopic metroplasty with drainage of the rudimentary horn hematometra provided long-term relief of the symptoms. The diagnosis was verified at diagnostic laparoscopy.
