A case of renal cell carcinoma detected by ultrasonography during the follow-up of polycystic kidney disease, was reported.
A sixty-seven-year-old male complaining of a left kidney mass had been submitted to exploratory laparotomy to rule out renal malignant tumor in 1976. Polycystic disease had been diagnosed according to the rinding of multiple cysts obserbed on the bilateral kidneys.
After a follow-up of 8 years, a solid mass was detected on the lower pole of the right kidney by ultrasonography. CT scan and selective renal angiography also indicated suspicion of right renal malignant tumor.
Right nephrectomy was performed and renal cell carcinoma (clear cell type) was confirmed pathologically.
These results showed that the ultrasonography was accurate for detecting the malignant tumor complicated with polycystic kidney disease.
