1

bilateral process which results in small, echogenic kidneys with noticeable loss of parenchymal thickness. Cortical thickness = minimum measurment of 1cm. May be difficult to distinguish from surrounding perinephric fat and retroperitoneal structures

chronic medical renal disease AKA chronic renal failure

2

benign, solitary renal tumor composed of blood vessels smooth muscle and fat cells

hypoechoic mass found in the renal cortex and can have posterior acoustic enhancement

no color doppler within tumor

angiomyolipoma

3

angiomyolipoma

80% in rt kidney and 80% in women

angio-blood vessels
myo-smooth muscle
lipoma-fat cells





4

multiple cysts of varying size located in the renal cortex and medulla. Bilateral, and can cause massively enlarged, asymmetrical kidneys. Often assocaited with cysts in the liver, spleen, pancreas and several small parts.

autosomal dominant polycystic kidney disease

5

solid parenchymal mass, isoechoic or hypoechoic, disrupt the renal cortex, peripheral vascularity (basket sign)

renal carcinoma

IVC and renal veins should be imaged for evidence of tumor extension

6

developmental anomaly of distal collecting ducts, causing urinary stasis with stone formation, usually asymptomatic and not found until young adulthood. Enlarged echogenic medullary (women in 20's with no symptoms)

medullary sponge kidney

7

diffuse calcuim deposits with the medulla, often seen in conjunction with MSK. Other primary causes are hyperparathyroidism, chronicnephritis, sickle cell (old man)

nephrocalcinosis

8

most common medical renal disease to cause acute renal failure. Would be differential diagnosis. Thinned cortex with enlarged, echogenic globs of medullary tissue (child who is dehydrated and has a fever)

acute tubular necrosis

9

outpouchings of the ladder wall, more commonly seen in older men w/ bladder outlet obstruction, neurogenic bladder disease or paraplegics

diverticulum

10

irregular, echogenic mass that projects into the lumen of the bladder or as a focal thickening of the wall. Will have blood flow

transitional cell carcinoma (95% of bladder tumors)

11

echogenic foci along bladder wall w/ posterior shadowing

bladder stones

12

echogenic parenchyma with loss of distinct medurllary

nephritis

13

necrosis of the glomerulus, cause is streptococcal bacteria

glomerulonephritis

14

network of capillaries which filters blood into the renal tubule

glomerulus

15

an infection of the calyces and renal pelvis, causes UTI, reflux, obstruction, diabetes. Possible to have focal pyelonephritis which appears as a focal echogenic area within the kidney characterized by lack of vascularity with the infected area.

pyelonephritis

16

most common kidney infection

pyelonephritis

17

if you put color on the kidney and part of it has color and part is hypoechoic

focal nephritis

18

most common ectopic kidney

pelvic kidney

19

bilateral fusion anomaly of the lower poles of the kidney which occurs during fetal development. Kidneys are closer to the spine and the inferior poles lie more medial.

horseshoe kidney

20

increased deposits of fat in renal sinus, renal cortex appears thinned. Appearance resembles chronic renal insufficiency disease.

sinus lipomatosis

21

enlarged kidneys with tiny cysts in the medullary and cortical regions, associated with billiary ectasia and hepatic fibrosis. Usually bilateral

autosomal recessive polycystic kidney disease

22

intact cortical rim, metaastatic from lymphoma

lymphoma

23

smooth, on stalk, do not shadow, do not move, most common tumor of gallbladder

polyps

24

GB-hyperplastic wall changes more echogenic than polyps, do not move, have ring down or comet tail artifact

adenomhyomatosis

25

GB-echogenic foci, multiple or single, shadowing, moveable

gallstones

26

GB packed with stones, no visible bile within the gallbladder lumen, very distinct posterior shadowing behind a thick, echogenic rim

Wall Echo Shadow (WES)

27

the whole wall of the gallbladder in incristed with calcium. Similar patter of distinct posterior shadowing in the area of the GB yet often w/o the heavy irregular echogenic anterior rim

porcelain gallbladder

28

mildly echogenic bile, can float, move as a ball, contain highly echigenic tiny foci can be seen along the gallstones

sludge

29

positive murphys sign, thickened wall with sonolucent area between the walls

acute cholecystitis

30

transient RUQ pain with no positive murphys sign more common than acute, is the result of multiple episodes of acute and with fibrosis developing in the wall

chronic cholecystitis
