Unicornuate uterus with a rudimentary horn is a rare congenital malformation of the female genital tract, asymptomatic because of lack of functional endometrium. This study presents a rare case of a non-communicating functional rudimentary horn. A 16-year-old unmarried Yemeni female adolescent with a history of irregular painful menstrual period visited Obstetrics and Gynaecology outpatient clinic. Pelvic ultrasound was conducted showing an asymmetrical uterine configuration with the non-communicating rudimentary horn on the right side. Laparoscopic excision of the horn was planned for the patient. Non-communicating rudimentary horn with functional endometrium should be considered as a differential diagnosis in the female adolescent with obstructive uterine symptoms. Early diagnosis is crucial. Using the laparoscopic approach, an expert surgeon prefers definitive management to excise the rudimentary horn. ER -
