The X-ray HSG (Hysterosalpingography) image shows a characteristic feature which is crucial in diagnosing the specific uterine malformation presented. In this case, the term "Unicornuate uterus" describes a congenital malformation where only one half of the uterus is typically present (resembling a single uterine horn), resulting from the incomplete development of one of the paired Müllerian ducts. Let's analyze the factors:
Unicornuate Uterus: This condition is identified by the presence of a single uterine cavity on an HSG. The image typically shows a solitary tubular structure, indicating a single horn of the uterus.
Septate Uterus: Would display a typical heart-shaped uterus with a division within the cavity due to a septum.
Uterus Didelphys: Appears as two separate uterine cavities and cervices, presenting a double uterus structure.
Bicornuate Uterus: Displays a uterus with two horns, appearing heart-shaped with an indentation at the top outer contour but less pronounced compared to didelphys.
Based on the characteristic features and differentiating factors, the correct identification of the X-ray HSG is a Unicornuate uterus.
