| Approximately 100 cases of collecting duct carcinoma have been reported in the medical literature. We herein report
on a case of collecting duct carcinoma of the kidney in a 75-year-old patient. The abdominal sonography depicted
a relatively poorly defined 7×6 cm sized, isoechoic mass lesion, as compared to the normal parenchyma, at
the left kidney lower pole and the affected kidney showed preservation of the reniform shape. CT revealed a heterogeneous
poorly defined low-attenuation mass that was mainly located in the medulla with involvement of the cortex
and the lower half of the renal pelvis. Retrograde ureteropyelography showed a filling defect at the lower renal
pelvis and severe narrowing of the left proximal ureter. We initially thought this lesion was invasive transitional cell
carcinoma. Subsequent surgery confirmed a collecting duct carcinoma. |
