Abstract
A case of multilocular renal cyst was reported. Left lumbar pain led to the discovery of a palpable mas of the lower pole of the left kidney visible at urography in a 54 yr old woman. At echotomography, alternation between dense and fluid areas made it possible to eliminate a solitary cyst. Renal arteriography was disturbing because of persistent slight peripheral hypervascularisation after the injection of angiotensin. Diagnostic doubt and the absence of any clearly defined limit between healthy kidney and pathological kidney led to nephrectomy. Histopathologically a thick capsule separated from the healthy kidney a series of cystic structures with no intercommunication between them, nor with the excretory system. Each cyst was lined with an endotheliform single layer epithelium with no renal tissue in the intercystic fibrous separations. The difficulty of offering an opinion about the etiopathogenesis of this lesion which some felt to be a dysplasia and others as a transitional form with nephroblastoma was emphasized.
