Fig. 1A.12-year-old girl with autosomal recessive polycystic kidney
disease. Longitudinal sonogram obtained in lower pole of left kidney using
high-frequency linear array transducer shows diffuse pattern of dilated
tubules (arrows).
Fig. 1B.12-year-old girl with autosomal recessive polycystic kidney
disease. Sonogram of entire kidney obtained using curved array transducer
resolves small hypoechoic structures although not to same degree as linear
array transducer.
Fig. 2A.Two patients with autosomal recessive polycystic kidney
disease and macroscopic cysts. In 7-year-old girl, solitary macroscopic cyst
(arrow) and dilated tubules are seen.
Fig. 2B.Two patients with autosomal recessive polycystic kidney
disease and macroscopic cysts. In 10-year-old boy, unusual pattern of
peripheral macroscopic cysts (arrows) is exhibited.
Fig. 3.4-year-old boy with autosomal recessive polycystic kidney
disease. Longitudinal sonogram of right kidney shows punctate foci of
increased echogenicity and dilated tubules but relatively preserved cortical
rim of tissue.
Fig. 5.9-year-old girl with autosomal recessive polycystic kidney
disease. Longitudinal sonogram of left kidney shows typical pattern of tubular
dilatation. In this case, however, this finding was seen in only one portion
of one kidney. Dilated tubules were seen nowhere else in either kidney.
