pathology

The uterine cavity ( Cavum uteri ) is not straight or convex (outward), but concave (curved inward) in the fundus (uterine crown), the muscle layer ( myometrium ) forms an indicated septum.

The cause is a disturbance in the embryonic development , in which the regression of the central, sagittal connective tissue septum is not completely complete after the merging of the Müller ducts .

distribution

The frequency is estimated at 3.9%.

Clinical manifestations

The clinical significance in the case of pregnancy is controversial.

diagnosis

The diagnosis can be made using sonography and / or magnetic resonance imaging .

Differential diagnosis

The uterus septus and uterus bicornis are to be distinguished .
