Up to one-third of fertile-age women with severe endometriosis suffer from colonic involvement. Transvaginal ultrasonography has become a first-line diagnostic tool for the study of the pelvis and more specifically for the diagnosis of pelvic endometriosis. Accuracy of pelvic ultrasound for deep endometriosis increases with operator experience, but the difficulties in the differential diagnosis with diseases that can afflict the bowel tract remain a challenge. We reviewed noteworthy cases referred for secondary level diagnosis suspected of bowel endometriosis in which the subsequent ultrasound led to an alternative diagnosis. This case series aims to highlight awareness for both experts and less-experienced operators the possible differential diagnoses of bowel lesions that initially resemble endometriosis.
