MULTIDETECTOR COMPUTED TOMOGRAPHIC EVALUATION OF ADNEXAL MASSES WITH HISTOPATHOLOGICAL CORRELATION

Abstract

Adnexal mass can arise from ovaries, fallopian tubes or any of the surrounding connective tissue and can be malignant or benign. Differentiating benign and malignant mass is imperative for management and is most commonly done by various imaging modalities. Materials and Methods: 36 patients who underwent multi-detector computed tomography and histo-pathological examinations of adnexal masses were selected for the study. The true positive, false positive, true negative and false negative cases were determined considering histopathology as gold standard. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated.

Results: Among 36 patients, 19 (52.8%) were diagnosed as benign masses and 17 (47.2%) as malignant masses on Computed tomography, whereas, 20 (55.6%) cases were diagnosed as benign masses, 13 (36.1%) as malignant masses and 3 (8.3%) as borderline masses on histopathology. The sensitivity, specificity, positive predictive value, negative predic- tive value and accuracy of Computed tomography in detecting benign adnexal masses was 95%, 93.7%, 95%, 93.7% and 94.4% respectively. Likewise, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of Computed tomography in detecting malignant adnexal masses was 92.3%, 82.6%, 75%, 95% and 86.1% respectively.

Conclusion: Multidetector computed tomography was found to be a valuable modality of imaging in differ- entiating benign and malignant adnexal masses with accuracy of 93.9%. Multidetector computed tomogra- phy can be helpful to differentiate various benign and ma- lignant adnexal masses based on typical characteristics.
