A case of perirenal lymphatic cysts demonstrated by computed tomography is reported. These lymphatic cysts, a histological subtype of lymphangiomata, are clearly visible as collections with clear fluidtype density surrounding both kidneys. The retroperitoneal localization of this rarity has been reported in the radiological literature, whereas, to our knowledge, the radiological demonstration of the perirenal localization has not. CT provides a unique method for direct radiological visualization of the cyst.
