Four infants are reported with unilateral replacement of the kidney by large cysts. These cases and six similar ones found in the literature show: (a) a large abdominal mass producing pressure symptoms only; (b) a normal contralateral kidney; (c) progressive increase in size of the mass; (d) adequate renal function after resection of the involved kidney.
