Longitudinal vaginal septum

ORPHA:180157Clinical subtype

What it is

A rare vaginal malformation characterized by the presence of a complete or incomplete septum dividing the vagina into two parallel cavities, resulting from failure of reabsorption of the midline uterine septum between the two fused Müllerian ducts during embryogenesis. Patients are often asymptomatic, but may present with menorrhagia, dysmenorrhea, dyspareunia, infertility, or spontaneous abortion. The condition may occur as an isolated malformation or in association with other Müllerian duct anomalies (such as septate uterus or uterus didelphys) or renal abnormalities.

Q52.1filed under a broader ICD-10 category — shared with 2 other rare diseases

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
