Magnetic Resonance Imaging of Sonographically Indeterminate Adnexal Masses: A Reliable Diagnostic Tool to Detect Benign and Malignant Lesion
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 1
Abstract
Introduction: Adnexal masses are a quite common clinical problem. Around 5-10% women undergo surgery for suspicious adnexal masses, but only 25% or less are malignant. Aims and Objectives: To study the sensitivity and specificity of magnetic resonance imaging (MRI) in differentiating sonographically indeterminate adnexal masses into benign and malignant, in considering biopsy as the reference standard. Materials and Methods: Our study is observational, analytical study with cross-sectional, data collection done from February 2015 to September 2016. 58 patients with sonographically indeterminate adnexal mass were selected as the study population. On the basis of ultrasound, we studied the distinguishing features of benignity and malignancy, origin and tissue characterization in MRI and the final diagnosis was confirmed with histopathology. Results: On MRI out of 58 masses, we diagnosed 30 masses as benign and 28 masses as malignant, however, on histopathological examination it was 27 and 31, respectively. The overall sensitivity and specificity of MRI to differentiate benign and malignant adnexal mass was 91.1% and 100%, respectively. The positive predictive value, negative predictive value, and accuracy were 100%, 90%, and 94.4%, respectively. Conclusion: In our study, MRI proved to be highly sensitive and specific in differentiating malignant from benign adnexal masses which were indeterminate on ultrasonography examination. Thus can be used to categorize indeterminate masses into benign or malignant and help the surgeon to plan surgery in the required persons, whereas those with benign masses can undergo conservative management.
