A complex malformation of the uterus: report of a tricavitated uterus

Objective

To report a case of a previously unknown anomaly of the uterus in a patient suffering from primary infertility.

Design

Case report.

Setting

University Medical Center.

Patient(s)

A woman with a tricavitated uterus.

Intervention(s)

During laparotomy both spherical structures and tubes were removed.

Main Outcome Measure(s)

Hysterosalpingography showed nonpatent tubes and dilatation in the proximal part of the tubes. By ultrasound, two spherical-shaped structures were found with a density resembling the density of myometrium and an inner lining similar to the endometrium.

Result(s)

Pathologic examination revealed that both spherical structures consisted of uterine muscle on the outside and functional endometrium on the inside. After two IVF cycles the patient became pregnant and delivered a healthy baby boy by cesarean section.

Conclusion(s)

The pathogenesis of this tricavitated anomaly of the uterus is discussed, but cannot be clearly explained, according to the classification for uterine malformations by the American Fertility Society.
