Unusual imaging presentations in renal transitional cell carcinoma

Abstract

Purpose: to report on unusual imaging presentations in renal transitional cell carcinoma (TCC)

Material and Methods: Imaging studies of 140 cases of pathologically proven renal TCC were retrospectively studied with the focus on unusual presentations

Results: Unusual imaging manifestations were found in 20 cases (14.3%). These findings were classified into 5 categories: perirenal abscesses or perirenal hematomas in 6 cases; parenchymal masses in 5; undue thickening of the hydronephrotic wall in 4; “tuberculoid” pyelograms in 3; and tumors with massive necrosis in 2

Conclusion: Deceptive imaging presentations may occur in renal TCC. Recognition of these presentations may help to prevent delay in diagnosis
