Endometriosis is defined as the presence of endometrial tissue outside the uterus. Endometriosis occurs almost exclusively in women between 20 and 45 years old, in particular up to 15 % of fertile women and up to 30 % of infertile women. Most women with endometrial implants on bowel serosa are asymptomatic; those with deep infiltrating implants may complain of abdominal pain, dysmenorrhea, dyspareunia, low backache, and localized tenderness. At sonography, intestinal endometriosis can appear as hypoechoic thickening or nodules/masses with irregular contours or, less frequently, as cystic lesions with anechoic fluid content and hyperechoic blood deposits, which often deforms the profiles of the bowel, and rarely causes complications such as invagination and volvulus.
