Preoperative imaging in renal masses: does size on computed tomography correlate with actual tumor size?

Objective To evaluate the discrepancy between tumor sizes determined from preoperative computed tomography (CT) and surgical specimens and its clinical implications. Material and method The charts of 86 patients who underwent surgical resection of a renal mass between 1995 and 2007 were reviewed retrospectively. Tumor size was determined both from preoperative CT and pathologic specimen. Histopathologic evaluation was done. Wilcoxon test was used to compare the mean radiographic tumor size on CT with the mean pathologic size. P
