Materials and Methods: The present study was carried out in 90 patients in the department of radio diagnosis and imaging, institute of medical sciences, Banaras Hindu University (BHU). The patients were referred from department of obstetrics & gynecology, institute of medical sciences. Majority of the referred cases were those who had clinical features of abdominal pain, abdominal lump, menstrual irregularity, ascites, and anorexia or weight loss & in whom adnexal mass was suspected clinically. Magnetic resonance imaging was performed using 1.5 Tesla MR Scanner, Magnetom Avanto (Siemens Healthcare). Results: Out of 114 masses, 17 (14.9%) were malignant. The benign adnexal masses were maximum in the age group 20 - 39 years (56/97, 57.7%), while malignant masses were mainly found in women ≥60 years of age (11/17, 64.7%). CA-125 level was grossly elevated in association with 35.3% of the malignant masses. On MRI, the sensitivity for the mass of ovarian origin was (97.7%) and specificity was (73.1%). The diagnostic accuracy was (92.1%). The mass of uterine origin had a sensitivity of (73.1%) and diagnostic accuracy (99.1%). Conclusion: MRI, because of its accuracy in identifying the origin of adnexal mass and characterizing the solid, hemorrhagic, fatty and fibrous content, may obviate surgery or significantly contribute to preoperative planning for a sonographically indeterminate mass. MRI is the state of the art imaging modality for evaluation of adnexal masses with an overall high diagnostic accuracy.展开更多
