Here are a few of the commonly seen abnormalities when we do a hysterosalpingogram (HSG).
To start with, here is a normal HSG
Endometrial polyps are probably the commonest abnormalities seen on HSG. These appear as filling defects and have to be differentiated from air bubbles. If there is any doubt, a hysterosonogram can be done to confirm the diagnosis.
An uterine septum can be associated with miscarriages. It is not possible to differentiate with certainty between an uterine septum and a bicornuate uterus on HSG.
A bicornuate uterus is another commonly seen uterine malformation. It can cause the baby to lie sideways or breech. It is associated with premature delivery.
A unicornuate uterus is another uterine anomaly where only one half of the cavity is present. It cannot be surgically corrected.
