The Rare Coexistence of Isolated Unilateral Adnexal Agenesis and Microperforated Hymen: A Case Report

Abstract

We share an 18-year-old patient with coexistence of isolated unilateral adnexal agenesis and microperforated hymen (MH). The rare type of partially obstructive congenital anomaly is MH. If the menstrual products or vaginal secretions are not fully evacuated from the vagina, the retained blood may become infected and lead to pyocolpos, tuboovarian abscess or systemic infection. Giant pyocolpos complicates the assessment of adjacent anatomical structures. In imaging methods, tubaovarian abscess-like appearance may occur. On laparoscopic observation; while describing the unilateral absence of the ovary and fallopian tube, we did not encounter any other anatomical malformations. Peroperatively, we excluded the prediagnosis of tubaovarian abscess and diagnosed pyocolpos. Mucopurulent fluid was drained by hymenotomy. No complications were observed in the postoperative six-month follow-up.
