Chronic Uterine Inversion Presenting as a Painless Vaginal Mass at 6 Months Post Partum: A Case Report

Uterine inversion is an abnormal protrusion of internal surface of relaxed uterus through the vaginal orifice. Its causes can be broadly classified as puerperal and non-puerperal with puerperal uterine inversion more common than non-puerperal uterine inversion. Acute inversions occurring immediately, or within 24 hours post-partum are the most common type. Chronic Uterine Inversions (CUI) occurring more than four weeks after the delivery are rare identities. There differential diagnosis includes prolapsed fibroids and endometrial polyp. Chronic nature of these inversions makes the restoration of the normal position of the uterus per vaginal difficult contrary to acute inversions which can be reposited more easily. We hereby present a case of 28-year-old lady who presented with a painless vaginal mass at 6 months post-partum. She was diagnosed as a case of CUI based on clinical and sonographic examination. Inverted uterus was successfully restored through per abdominal approach. The presentation of CUI as a painless vaginal mass at delayed post-partum period is rare and therefore reported.
