In this case:

• the upper vagina is more distended than the uterus
• the uterus appears normal with no Müllerian duct anomalies
• both kidneys are normally situated with no congenital anomalies

These findings indicate most likely an isolated lower vaginal atresia, not considered as a type of Müllerian duct anomaly. It occurs from a failure of recanalization of the urogenital sinus.
