Manchanda DOI: 10.26044/ecr2024/C-16161 Learning objectives Endometriosis is one of the most common causes of pelvic pain and infertility in young females seen in routine practice. The purpose of this exhibit is toa)familiarise radiologists with the typical and atypical radiological features,b)look at usual and unusual sites;c) systematically approach the suspected case.

Clinical history along with imaging forms the mainstay of diagnosis. Transvaginal ultrasound (TVS) is done in the initial evaluation of the patient with suspected pelvic endometriosis. Magnetic Resonance Imaging (MRI), however, helps in the complete assessment of endometriosis and gives a roadmap for any surgical intervention. In addition, malignant transformation can also be diagnosed early with MRI. Thorough knowledge of the possible site involvement and the variability in imaging appearance is a must for an accurate assessment of the disease. Findings and procedure details Endometriosis is defined as the presence of endometrial tissue outside the uterus. It is a common gynecological disorder, affecting around 10 percent of women of reproductive age; and approximately 5 percent of post-menopausal women, with a history of exogenous estrogen replacement. [1]The ectopic endometrium will undergo various degrees of cyclical hemorrhage due to hormonal stimulation, which will lead to pain and typical appearance. [2]Sites of endometriosis can be: Intrapelvic (more frequent): ovaries (most common ); may also involve uterosacral ligaments, cul-de-sac, serosal surfaces, fallopian tube,...

Endometriosis can have different radiological appearances with predictable and unpredictable sites and can have various close mimickers, so importance lies in presurgical accurate diagnosis for effective management.
