Decoding the role of MRI in evaluation of endometriosis and its mimics

Background: Endometriosis is presence of endometrial tissue at a site outside the uterus. Endometriosis is a common and important entity affecting women of reproductive age group. Diagnosis of endometriosis is a combination of clinical history combined with non-invasive and invasive imaging. Its differentiation with other mimicking pathologies becomes crucial in proper diagnosis and management of the patients with overlapping symptoms. Aim was to assess the role of MRI in characterising endometriosis and differentiating it from its various mimics. Methods: The study was performed on 30 patients with complaints of pelvic pain, dysmenorrhea and patients suspected of endometriosis in Dr. Ram Manohar Lohia Hospital, New Delhi from January 2022 to January 2023 under ultrasound and MRI SEIMENS 3T machine. Radiological characteristics were studied and evaluated. Descriptive and inferential statistical analysis was made. Results: Wide spectrum of cases were studied and characteristic imaging features of each mimic was evaluated. Conclusions: MRI is sensitive in detecting endometriosis and differentiating it from its various mimics. MRI being non-invasive can be easily done and therefore plays a crucial role in making correct diagnosis combined with clinical history.
