Abstract

Accessory Cavitated Uterine Mass is  a rare form of mullerian developmental anomaly that is often missed as a diagnosis, leading to persistent pelvic pain, painful menstruation, and infertility in young women, generally those under the age of thirty.These lesions are frequently called "uterus-like masses" because they lack contact with the normal uterine cavity and contain a functioning endometrial lining encircled by smooth muscle cells that resemble the myometrium.1The primary endometrial cavity, fallopian tubes, and ovaries appear to be normal. Past reports classified it as a juvenile cystic adenomyoma, isolated cystic adenomyoma, and a cavitated uterus-like mass within the myometrium, which are now considered as ACUM. This entity is thought to be caused by the duplication and persistence of a Mullerian duct segment at the level of the round ligament attachment, which may be brought on by Gubernaculum dysfunction.2
The specific typical population is not described in the literature because most of the reports on ACUM are based on case series and case reports. Because of its rarity, it is uncertain how common this illness really is.. Although women under 30 account for the majority of recorded instances of ACUM, older persons have also been observed to exhibit symptoms of the disease.  ACUM patients may or may not have had dysmenorrhea. Women with ACUM may still exhibit symptoms like dyspareunia even if they don't exhibit any.3
