Role of multislice CT in diagnosis of parenchymal renal masses

ABSTRACT

The challenges of renal tumoral imaging include not only reliable differentiation between benign and malignant lesions but also accurate delineation of the extent of the disease to ensure optimal treatment planning. The aim of this study is to evaluate the role of multiphasic multidetector CT in characterization of parenchymal renal masses and identify the role and accuracy of MDCT in detection and surgical planning of renal masses as one single modality, using the state of art of CT. The study included 20 patients out of 120 patients with parenchymal renal masses underwent MDCT with single holus technique and four phases including unenhanced phase, arterial phase, nephrographic phase and excretory phase. According to MDCT findings we can classifyparenchymal renal masses into 14 malignant renal masses [10 renal cell carcinoma RCC and 4 Wilm's tumor] and 6 benign renal masses [2 angiomylipoma AML, 2 xanthoglumerulonephritis 2 renal abscess,]. MDCT imaging can differentiate between different types of parenchymal renal masses
