Evaluating the Accuracy of Computed Tomography in the Diagnosis of Renal Masses
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 3
Abstract
Objectives: To evaluate the accuracy of Computed Tomography in differentiation of benign and malignant renal masses. Methodology: Aprospective study was conducted in the Department of Radio diagnosis, Govt. Medical College, Kottayam over a period of 18 months from May 2015 to November 2016. Study population included 46 patients who were referred for CT scan of abdomen with clinical suspicion of renal mass. Results: Of the 46 cases studied, majority (73.9%) were malignant renal masses among which Renal Cell Carcinoma was the predominant diagnosis (50%). The diagnostic accuracy of multiphasic Computed Tomography was found to be 86.9% for differentiation of benign and malignant renal masses with a sensitivity of 94%, specificity of 66.6%, Positive Predictive Value of 88.9% and Negative Predictive Value of 80%. Some of the CT parameters were found to have statistically significant association with various renal masses. Irregular shape and ill defined parenchymal interface of renal masses on CT were found to have statistically significant association with malignancies and RCCs. Exophytic growth pattern, heterogenous and early washout enhancement pattern & presence of perilesional collaterals were also found to be associated with RCCs. Intrarenal location of lesion along with renal pelvic / ureteric involvement was found to be significantly associated with TCC. Conclusion: Computed Tomography is an accurate imaging modality for the evaluation of renal masses and thus an important prerequisite for proper patient management
