This ectopic tissue undergoes cyclical hormonal changes similar to the eutopic endometrium, leading to inflammation, scarring, and adhesions. Clinically, the condition is strongly associated with chronic pelvic pain, dysmenorrhea, dyspareunia, and infertility, and it often has a significant impact on the quality of life.

Radiologists should adopt a systematic approach, provide structured reports, and pay particular attention to critical anatomical regions—such as the ileocecal area—in order to identify coexistent Crohn’s disease or differentiate it. This review offers comprehensive guidance on optimizing MRI examinations, ensuring high-quality imaging, and delivering accurate interpretation with standardized reporting, ultimately facilitating more effective patient care and surgical planning.\nPersonal information and conflict of interest\nF.
