Introduction: Uterus unicornis or hypoplastic uterus is a condition which occurs after agenesis or hypoplasia of one of the Müllerian ducts. Lateral disposition, reduction in the size of the uterus, and complete loss of its usual pear shape characterize it. Typical for this malformation is a decrease in the transverse and linear diameters of the fallopian tube. The uterus is positioned on the same side as the individual`s single ovary.
Materials and methods: A 36-year-old female with primary infertility and uterine malformation was hospitalized in Specialized Hospital of Obstetrics, Gynecology and Neonatology - Varna with abdominal discomfort and short history of In Vitro Fertilization & Embryo Transfer (IVF-ET) in another hospital. The transabdominal ultrasound conducted shortly after the admission showed presence of a right ovary, atypically located close to the liver. Theca lutein cysts and a small volume of ascitis were registered.
Results: Patient was admitted to the gynecological unit for close monitoring and intensive care. Infusions were started combined with anticoagulation therapy. On the 10th day she was signed out of the hospital with stable status and minimal abdominal discomfort. The physical examination two weeks after presented right ovary with normal size and absence of the first indicated cystic formations and ascitis.
Conclusion: Congenital abnormalities of the Müllerian ducts are extremely varied and the existing categorisation cannot always determine the abnormality. As it was shown in the presented case of the patient with hydrosalpings and doubts for pretubar adhesion, these abnormalities demand an endoscopic approach for both diagnosing and treatment.
