This case report describes a young woman suffering from severe, treatment-resistant dysmenorrhea who was diagnosed with an accessory and cavitated uterine mass. The condition, a rare Müllerian anomaly characterized by a non-communicating uterine mass lined by functional endometrium, was identified preoperatively via MRI and confirmed during surgery at the insertion of the right round ligament. The patient underwent a total laparoscopic hysterectomy, which successfully resolved her symptoms. This paper is centrally about adenomyosis-like pathology within a specific Müllerian anomaly context, as the functional endometrial lining of the accessory mass causes cyclic pain similar to adenomyosis or endometriosis, though it is technically classified as a distinct structural defect rather than classic endometriosis.

Abstract

Accessory and Cavitated Uterine Mass (ACUM) is a condition defined by the presence of a non-communicating uterine mass close to the insertion of the round ligament. ACUM is a rare Müllerian anomaly found in young women and is diagnosed by the presents of a central cavity in the uterus, lined by functional endometrium, and surrounded by a ring of smooth muscle. In most cases, surgical treatment is recommended due to severe dysmenorrhea. Herein, we present a case of a woman with severe dysmenorrhea since adolescence which was not relieved with any form of hormonal treatment. ACUM was suspected preoperatively based on MRI findings, and she was treated with total laparoscopic hysterectomy. A uterine mass was found at the insertion of the right round ligament during surgery. All her symptoms improved after resection.
