Role of Multidetector Ct in Characterization of Renal Mass

Abstract

Background: Due to rapid pace in development of imaging techniques and increasing number of investigations being done, more number of renal masses are discovered incidentally during evaluation of unrelated or unspecific symptoms. Hence it is vital to differentiate neoplastic and non-neoplastic masses.

 Among the neoplastic masses, there is a need to differentiate benign and malignant masses so that appropriate treatment strategies like nephron sparing surgery, radio frequency ablation etc. can be planned at an early stage and avoiding unnecessary radical treatments for improved patients survival.

Methods: many non-consecutive patients belonging to all ages and both sexes admitted into the various clinical departments of Hilla General Teaching Hospital who had presented with suspected renal mass by clinical signs and symptoms were examined on CT with protocol were included in our study.

Results: CT is the standard imaging modality of choice for characterization and staging of  the renal lesions.

Conclusions: Computed Tomography (Multidetector) is the imaging modality of choice for further evaluation and characterization. Contrast enhanced CT is done in four phases viz., unenhanced, corticomedullary, nephrographic and excretory phase especially in cases of malignancy like renal cell carcinoma and benign conditions like angiomyolipoma and abscess is sufficient. However histopathological is the gold standard for diagnosis of various renal masses.
