A woman had an unusual mullerian anomaly with a septate uterus, cervical du
plication, and longitudinal vaginal septum. Gynecologists should be aware o
f the possibility of cervical duplication associated with uterine septum an
d not didelphic uterus, as this disorder in a patient with infertility or r
ecurrent miscarriages can be treated surgically by resection of the uterine
and vaginal septum. Embryologic explanations may account for the occurrenc
e of the anomaly.
