Both kidneys are of normal site, size and shape. They show increased parenchymal echo-pattern with decreased cortico-medullary differentiation. No stones or masses. No pelvicalyceal dilatation bilaterally.
The right kidney averages 6.5 x 2.6 cm (Length x TS) with a parenchymal thickness of 1 cm.
The left kidney averages 7 x 3.2 cm (Length x TS) with a parenchymal thickness of 1.2 cm.
Diffuse bilateral renal tiny parenchymal cysts, largest averages 3 mm with increased parenchymal echopattern, suggestive of autosomal recessive polycystic kidney disease.
Minimal bilateral perirenal collections, related to the lower pole of both kidneys, more on the right side, that raise the possibility of associated bilateral renal pyelonephritis.
The liver is average in size (7.2 cm in MCL) with mild fibrotic changes. The spleen is of average size. The gallbladder is normal.
