Longitudinal vaginal septum

Dr Henry Knipe and Dr Priya Cherian et al.

A longitudinal vaginal septum is a congenital abnormality of the vagina where a septum divides it into two parallel cavities.

Usually asymptomatic unless obstructed and if obstructed it may cause cyclic pelvic pain. Amenorrhoea may occur if both cavities are obstructed 1.

It is due to failure of lateral fusion / reabsorption of the paired Mullerian ducts during development of the vagina.

Associations

Typically arises with other Mullerian duct anomalies such as septate uterus and uterus didelphys 2. However, it can also arise as an isolated anomaly 3

It may be difficult to diagnose in the absence of obstruction.

MRI

T2 weighted images demonstrate hypointense septum (relative to the hyperintense secretions/blood) with two hemivaginas present 1,3
