Background: Accessory and cavitated uterine mass (ACUM) is a rare form of female genital malformation associated with gubernaculum dysfunction. The clinical picture of the disease is characterized by severe dysmenorrhea and chronic pelvic pain which do not respond to conservative therapy. When performing ultrasound or MRI of the pelvic organs, ACUM appears as a large mass in the pelvic cavity.
Case report: The article presents a clinical case of complex diagnosis and surgical treatment of ACUM in a 30-year-old nullipara who presented to the clinic with severe dysmenorrhea and recurrent pelvic pain. Planned laparoscopic excision of ACUM was performed after a follow-up examination. The histological examination revealed the presence of a secretory endometrium surrounded by muscle tissue. In the postoperative period, there was a complete resolution of the symptoms of dysmenorrhea and pelvic pain.
Conclusion: Verification of the diagnosis presents significant difficulties due to the rare prevalence of pathology and the lack of alertness among specialists. Magnification of the image and less traumatic intervention make laparoscopic and robotic surgery the most preferred method for the treatment of ACUM.
