Uterine Septum
Pronunciation: YOO-ter-ine SEP-tum
A congenital malformation where fibrous tissue divides the uterine cavity, potentially affecting fertility and pregnancy.
Full Definition
A uterine septum is the most common congenital uterine anomaly, characterized by a fibrous wall that partially or completely divides the uterine cavity. This malformation results from incomplete fusion or resorption of the müllerian ducts during fetal development. Septate uteri are associated with increased rates of miscarriage, preterm birth, and malpresentation. Diagnosis is typically made through MRI, 3D ultrasound, or hysteroscopy. Treatment involves hysteroscopic septum resection, which can significantly improve reproductive outcomes. The septum differs from a bicornuate uterus by having a normal external uterine contour.
Usage
Usage note: Distinguished from bicornuate uterus by normal external fundal contour on imaging.
