Uterus didelphys. Ultrasound diagnosis in the case of an adnexal mass as a presenting symptom in early pregnancy.

Uterine anomalies are one of the various processes in the pelvic organs which present themselves as adnexal masses in pregnancy. In pregnancy associated with congenital uterine anomalies, complications are likely to occur. Ultrasonography is of great importance in early recognition of the anomalies, which can prevent unnecessary surgical intervention. A case of ultrasonic detection of uterus didelphys with unicavitary pregnancy is described.
