An Unusual Condition Simulating Malignancy: A Patient with FibroepithelialPolyp of the Renal Pelvis Covered by the Blood Clot

Fibroepithelial polyp of the renal pelvis is a rare cause of hematuria, and is frequently mistaken for transitional cell carcinoma. We report a 78-year-old female presented with intermittent painless gross hematuria initially suggestive of transitional cell carcinoma. CTU showed high density shadow in the right renal pelvis and proximal ureteral lumen. IVU and retrograde urograph showed a filling defect in the right renal pelvis and proximal ureter that was found to be a fibroepithelial polyp of the renal pelvis. This case demonstrates a rare cause of gross hematuria that should be considered when the imaging findings and presentation are atypical for more common etiologies of hematuria.
