This case report describes a 39-year-old virgin woman with a four-year history of right inguinal pain, whose abdominal ultrasound revealed a hypoechoic mass, leading to a preoperative diagnosis of inguinal endometriosis.

This paper is a case report describing right-sided inguinal canal endometriosis identified using ultrasound, focusing on imaging findings in a single patient. The authors present the ultrasound features associated with endometriotic involvement in the inguinal region. As an individual case report, the study’s findings are limited by lack of generalizability and does not provide comparative or mechanistic analysis. This paper is centrally about endometriosis — specifically, ultrasound-detected right-side inguinal canal endometriosis.

Abstract

Background: The first case of inguinal endometriosis was described by Cullen. Endometriosis in the round ligament could be in the pelvic or inguinal area and is a rare disease occurring in 0.6% of women. Women with inguinal endometriosis have a painful inguinal mass during menstrual cycles and they mostly have a history of surgery. The right side is more commonly involved in inguinal endometriosis than the left side (90-94%). A history of gynecologic or abdominal surgery is common in women with inguinal endometriosis. Case presentation: In our case, a 39-yr-old virgin woman presented with localized pain in the right inguinal that had been present for 4 yr. She did not have any history of previous surgery, and abdominal ultrasonography showed a hypoechoic mass with minimal vascularity. Inguinal endometriosis was correctly diagnosed by two expert radiologists preoperatively, and she underwent laparoscopic surgery. Conclusion: Considering inguinal endometriosis in the differential diagnosis of women with inguinal masses is important, even if there is no history of gynecologic or abdominal surgery.
