RADIOLOGY: GENITOURINARY: GU: Case# 32985: URETERAL TRANSITIONAL CELL CARCINOMA. A 52 year old male with recent onset of right lower quadrant pain radiating to the right groin, associated with gross hematuria. Intravenous urogram at an outside hospital reported showed a right ureteral abnormality. On noncontrast series, no calcifications are identified in the region of either ureter. Following contrast administration, both kidneys appear normal. There is a 1 cm soft tissue attenuation filling defect in the right ureter at the level of L5-S1 (image 3) with dilation of the ureter at the filling defecting level. No other filling defects are present in either ureter or bladder. The lung bases are clear. The liver, gallbladder, spleen, pancreas, adrenals, stomach, small and large bowel appear normal. No free intraperitoneal fluid, adenopathy or skeletal lesions are seen.
