Deep infiltrating endometriosis: retroperitoneal endometriosis-a case report

We herein present a rare case of DIE-a retroperitoneal endometriosis and describe the process of the laparoscopic management. For retroperitoneal masses closely adherent to the pelvic wall, clarifying the course of the ureter is of great importance, and collaboration with urologic surgeons may be necessary when needed. Because there is no-specific imaging features, the benign or malignant nature of the mass might be suspected before surgery.
