Quadro-Cornuate Uterus.

Congenital malformations of the female genital tract are a group of miscellaneous deviations from normal anatomy with diverse spectrum. Mullerian anomalies are thought to be present in 0.5% of female population. Three quarter of women remain asymptomatic, the remaining quarter presents with a variety of symptoms including primary amenorrhea, cyclical pain, severe dysmenorrhea, pelvic mass, ectopic pregnancy, infertility and recurrent miscarriages. The American Fertility Society (AFS) classification has been the most widely used classification for categorizing these abnormalities. Recently, European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) proposed another classification system of female genital anomalies which provides a comprehensive description and categorization of almost all of the currently known anomalies. This case report describes a 23-year, married, parous woman with severe dysmenorrhea. Workup revealed a right adnexal mass which preoperatively was consistent with noncommunicating horn(s) of uterus. Peroperatively a new entity, a uterus with four cornua, was seen.
