Fig GU 28-1 Simple renal cysts. Anechoic fluid-filled masses (C) with strongly enhanced posterior walls.
• 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
Fig GU 28-3 Parapelvic cyst (C). Fluid-filled collection that displaces but does not separate the pelvocalyceal echo complex.
• Fig GU 28-4 Hydronephrosis. Obstructed renal pelvis and calyces produce the sonographic pattern of multiple communicating cystic structures (arrows).25
• Fig GU 28-5 Multicystic dysplastic kidney. Sagittal sonogram demonstrates the cystic kidney (K). Note the absence of communication between the cystic structures.27
Fig GU 28-6 Hematoma. Extensive anechoic collection (H) about a renal transplant.
