title: Caliceal diverticula developing into simple renal cyst.
abstract: Although common in adults simple cortical renal cysts are rare in children. Caliceal diverticula are rare in adults and children. A case of a caliceal diverticulum apparently sealing off and becoming an isolated simple cyst in the renal parenchyma has been reported as an unusual complication of caliceal diverticula. There have been 2 other cases of caliceal diverticula becoming sealed off reported in the literature, although neither progressed to frank cysts. We report 2 cases of definite caliceal diverticula progressing to simple renal cortical cysts.
