This case report describes a 47-year-old woman with no prior gynecologic history who was evaluated for a pelvic mass. Magnetic resonance imaging suggested adenomyosis and a mass near the uterus, with imaging features that led clinicians to suspect polypoid endometriosis preoperatively. Laparoscopy identified a dark-red pelvic mass adjacent to the uterus, and a laparoscopic hysterectomy was performed, after which histology confirmed polypoid endometriosis together with adenomyosis. This paper is centrally about endometriosis — it reports a case of polypoid endometriosis resolved by laparoscopic hysterectomy, with adenomyosis identified on imaging and histology.

Abstract

We report a case of polypoid endometriosis, which was resolved by a laparoscopic hysterectomy. A 47-year-old woman without any previous history of a gynecologic disorder presented at our hospital for evaluation of a pelvic mass. Magnetic resonance imaging revealed adenomyosis and a mass adjacent to the uterus. The mass had low signal intensity on T1- weighted imaging and high signal intensity on T2-weighted imaging. Polypoid endometriosis was suspected preoperatively. Laparoscopy revealed a dark-red pelvic mass adjacent to uterus. We performed a laparoscopic hysterectomy. Histologic examination revealed polypoid endometriosis with adenomyosis. To the best of our knowledge, this is the first report of polypoid endometriosis was resolved by a laparoscopic hysterectomy.
