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.
