Introduction: An accessory uterine cavity can be an unusual cause of persistent cyclical pelvic pain.

Case: 25 year old female with longstanding cyclical dysmenorrhoea. No improvement on oral contraceptive pill, depot or Mirena IUD despite amenorrhoea.

Management: Hysteroscopy showed a normal cavity with both ostia seen. Diagnostic laparoscopy showed a 3cm uterine mass adjacent to left round ligament and tube. Ultrasound showed 24mm left cornual thick walled mass with central haemorrhagic material and a normal renal tract. MRI diagnosed an accessory uterine horn with haematometra.

Operative laparoscopy was performed to excise the accessory uterine cavity.

The patient made an unremarkable post operative recovery with resolution of her symptoms. Histopathology confirms myometrium and endometrium consistent with an accessory uterine cavity.

Discussion: Congenital anomalies of the uterus should be considered in the differential diagnosis of persistent cyclical pelvic pain. Accessory uterine cavity can be an unusual subtype. Ultrasound and MRI can aid in the diagnosis. Definitive laparoscopic surgical management can result in resolution of symptoms.

Imaging and operation pictures/video will be presented.
