[The echographic diagnosis of a rare congenital uterine anomaly (uterus unicornis with a rudimentary noncommunicating horn)].
A correct diagnosis of a unicornuate uterus with rudimentary noncommunicating horn, complicated with haematometra in a 12-year-old patient, was established after a detailed sonographic examination. The diagnosis was confirmed by diagnostic laparoscopy and surgical excision the rudimentary horn was undertaken. The case is interesting with the fact that several months before the patient's referral to our hospital laparotomy was performed because of persistent and progressive abdominal pain and suspicion for acute appendicitis. The uterine anomaly present was described as uterus duplex. It may be concluded that: The diagnosis of uterine anomalies may be extremely difficult for the inexperienced operator even at laparotomy. This is important since the management of congenital uterine anomalies depends on their type and differs a lot. Any mistakes in this aspect may be fatal for the patient in her further life. The ultrasound examination performed by an experienced sonographer may give precise information about the nature of the defect thus making the task of the operator easier. The final diagnosis of the uterine anomalies is based on the combined interpretation of the data from the patient's history, the sonographic examination, the diagnostic laparoscopy and other methods of investigation if necessary.
