Uterus is a slight variation of the uterus and is one of the abnormalities of the Müllerian duct. However, an ectopic uterus is less likely to affect reproduction.
1. What is an arcuate uterus?
Uterus is a slight variation of the uterus, which is one of the Müllerian duct abnormalities, but is generally classified as an anatomical variant of the uterus. In fact, a curvilinear uterus is a uterine abnormality with little association with reproductive risks. This condition can be identified with an ultrasound of the uterus or an MRI scan.
Pathologically, the ectopic uterus is characterized by a slight involution of the endometrium in the fundus. This happens because the uterine septum is not completely absorbed to become a normal uterus. It is the most common Mullerian duct defect, affecting 3.9% of the general population.

MRI images can show that the normal ectopic border is maintained, there is a wide and regular indentation at the base of the myometrium that is consistent with normal uterine muscle.

3. Differential diagnosis of ectopic uterus
3.1. Uterus with septum
Uterus and septum are both uterine malformations. In which the septal uterus appears due to less absorption of the septum compared to the uterus.
3.2. Two-horned uterus
The ectopic uterus can be distinguished from the bicornuate uterus by the continuity of the lateral fundus.
Uterus is a slight variation of the uterus and is one of the abnormalities of the Müllerian duct. This is a uterine malformation that is less likely to affect reproduction, but when there are abnormal signs, you should go to medical facilities for examination and accurate diagnosis.
