Unilateral acquired renal cystic disease and neoplasia in a patient with renal artery stenosis.

We report a case of a sixty-two-year-old woman with longstanding unilateral renal artery stenosis in whom acquired renal cystic disease (ARCD) and neoplasia developed. ARCD has been frequently reported in the hemodialysis and peritoneal dialysis patients, but rarely reported in the nonuremic patient. To our knowledge it has not been previously reported in a patient with unilateral renal artery stenosis.
