echo free fluid regions indented and shaped by the surrounding organs 1st fills pouch of douglas before is ascend to the paracolic gutters, major flow from the pelvis is via the right side small bowel loops sink and float within the fluid

33
Q

occur in 5% of people over the age 50 often seen in patients with autosomal dominant polycystic kidney desease

A

hepatic cysts or liver cysts (IDK)

34
Q

appearance of liver cyst

A

smooth, thin, well defined walls round or oval anechoic increased posterior enhancement (though transmission) single or numerous

35
Q

irregular, hypoechoic lesion, dilated pancreatic duct, liver and para-aortic nodes

A

pancreatic adenocarcinoma most often in head and usually cause obstruction of CBD, GB, and hydrops and jaundice

36
Q

symptoms of pancreatic adenocarcinoma

A

ABD pain back pain painless jaundice weight loss

37
Q

pancreas appears inflamed and releases enzymes into the surrounding pancreatic tissue. Hypoechoic and edematous with irregular borders. Pancreatic duct may become enlarged

A

acute pancreatitis

38
Q

pancreas appears hyperechoic with echogenic foci andomly dispersed throughout the gland

A

chronic pancreatitis

39
Q

an accumulation of pancreatic fluid and necrotic debris confined by the retroperitoneum

A

pseudocysts

40
Q

common causes of pseudocysts

A

acute pancreatitis chronic panreatitis pancreatic trauma pancreatic ductal obstruction pancreatic neoplasms

41
Q

most common cause for pseudocysts in children

A

ABD trauma

42
Q

focal lesions in the spleen resulting from previous infections

A

splenic calcifications (granulomatous infection)

43
Q

appearance of granulomatous infection (splenic calcifications)

A

bright echogenic lesions with or without shadowing

44
Q

most common cause of spenic calcifications (granulomatous infections)

A

tuberculosis and histoplasmosis

45
Q

common congenital anomaly of the spleen

A

accessory spleen

46
Q

appearance of accessory spleen

A

well circumcised typically rounded and isoechoic with the spleen typically found at the lower splenic pole or near the hilum

47
Q

priminent infolding of the renal cortex which indents the renal medullary. Columns have an echogenicity similar to renal paenchyma and are continous with the renal cortex. Do not distort the renal cortex

A

column of bertin

48
Q

bulge of the renal cortex that occurs on the lateral border of the kidney. more often on the left than the right. identical echogenicity as renal corted and can mimic a cortical tumor. Cortical border is intact and hump will contain normal appearing pyramid structures. Little bit of fat in hump

A

dromedary hump

49
Q

developmental varient seen more in children and sometimes in adults. Typical smooth cortical border appears indented or undulated between the calyces, giving the kidney surface a lobulated appearance. Cortical borders are still intact and parenchymal thickness is uniform through kidney. Cases of renal scarring and/or insufficiency will demonstrate cortical thinning

A

fetal lobulation

50
Q

on both the long and transverse images the central renal sinus appears as two echogenic regions that are separated by a cleft or normal renal tissue. On continuous transverse imaging one image will appear to have no central medullary tissue only parenchymal tissue.

Q

appearance of nephrolithiasis

A

echogenic foci with posterior acoustic shadowing stones within the cortex are easier to distinguish than stones within the medullary and prominent renal sinus. Fat with weak shadowing can mimic stones

57
Q

appearance of parapelvic cysts

A

anechoic cyst located in the renal hilum will distort the renal sinus fat and does not communicate with the collecting system well defined but will have irregular borders caused from the compression of the adjacent renal sinus structures enlarge and cause renal obstruction

A

renal dilation must have connecting calyces to by hydro important to follow the renal dilation as distal as possible in an attempt to determine the cause and location of the hydro

check for bilateral ureteral jets
