The accuracy of MDCT for staging of Wilms’ tumor

Abstract

Aim of workTo evaluate the accuracy of multidetector computed tomography (MDCT) in staging of Wilms’ tumor. Patients and methodsThis prospective study was performed on 32 children (age range 4–8years), having renal mass lesion, were studied with multidetector computed tomography (MDCT). Axial and multiplanar imaging were evaluated. All tumors were staged according to NWTS-4 classification. MDCT diagnosis was compared with surgical and pathohistological data. ResultsAll the cases were staged according to the fourth trial of the National Wilms’ tumor Studies (NWTS-4). The 32 cases were found to have 36 tumors (4 cases were bilateral masses), 4 tumors were diagnosed as stage I, 9 tumors were diagnosed as stage II, 7 tumors as stage III, 8 tumors stage IV and 8 tumors were stage V. ConclusionIn conclusion, MDCT represents a reliable diagnostic method for evaluating Wilms’ tumor and it is accurate and sensitive in diagnosing stages I, IV and V, but is not as accurate in the diagnosis of stages II and III and has poor correlation with histopathological data.
