4. • Fig GU 28-2 Adult polycystic kidney disease.
(A) Parasagittal sonogram of the right kidney
(PK) shows a random distribution of multiple
cysts that vary dramatically in size. The normal
reniform contour is maintained. (B)
Parasagittal sonogram in a young,
asymptomatic member of the family shows
multiple cysts (CR, CL) in the right kidney (R)
and liver (L). (D, diaphragm; H, head.)2
5. Fig GU 28-3 Parapelvic cyst (C). Fluid-filled collection that
displaces but does not separate the pelvocalyceal echo complex.
6. • Fig GU 28-4 Hydronephrosis. Obstructed renal
pelvis and calyces produce the sonographic
pattern of multiple communicating cystic
structures (arrows).25
7. • Fig GU 28-5 Multicystic dysplastic kidney.
Sagittal sonogram demonstrates the cystic
kidney (K). Note the absence of
communication between the cystic
structures.27

transplant.
