Extragenital endometriosis: assessment with MR imaging. A pictorial review

摘要

Endometriosis is a gynaecologic disease characterized by endometrial tissue outside the uterine cavity. Commonly it affects the pelvic organs. When endometrial nodules or plaques are localized in sites other than the uterus or ovaries, it is termed extragenital endometriosis. Adequate pre-operative assessment is essential for treatment planning. MRI is a non-invasive method with high spatial resolution that allows the multiplanar evaluation of genital and extragenital endometriosis. Herein, we present a pictorial review of a variety of extragenital endometriosis cases, all of which can be encountered in clinical practice.
