Q
A 25-year-old female patient presents to the sonography department for a complete abdominal sonogram. She complains of right lower quadrant pain and nausea. The right upper abdomen appears normal.

B) dilated extrahepatic ducts
C) Courvoisier gallbladder
D) diffuse thickening of the common duct
dilated intrahepatic ducts
Caroli disease is a rare inherited disorder characterized by dilatation of the intrahepatic bile ducts.
There are two types of Caroli disease, the most common being the simple, or isolated case where the bile ducts are widened by ectasia.
The second, which is more complex, cause is known as Caroli Syndrome. This complex form is also linked with portal hypertension and congenital hepatic fibrosis. The differences between the causes of the two cases have not yet been discovered.
Caroli disease is also associated with liver failure and polycystic kidney disease.

complicates the lesser sac
31
The portion of the pancreas that lies posterior to the SMA and vein is the:
uncinate process
32
Occasionally, a pseudocyst may have internal echoes and be confused with an abscess. The distinguish between the two, one should look for:
A) calcifications
B) fluid in the lesser sac
C) gas
D) septations
gas
Pseudocysts can have all of the features mentioned above....but when you add "gas" to the picture, the pseudocyst is infected and air production means an abscess.
33
Chronic pancreatitis may be associated with all of the following except:
A) increased echogenicity
B) increased cystic duct
C) calcifications
D) dilated pancreatic duct
E) decrease in pancreas size
increased cystic duct
34

37
The common bile duct is joined with the pancreatic duct before entering the:
second portion of the duodenum
38
Which of the following will displace the SMA anteriorly?
left renal vein thrombosis
You should have been looking for 'uncinate process' here...but in not finding it you must think about all parts of the body. A pancreatic head mass would not move the SMA anteriorly--perhaps posteriorly and medially depending on the postition of the mass. If you cannot visualize this you must pull out your diagrams.
39

A) pancreatic duct obstruction
B) acute pancreatitis
C) liver disease
D) obstruction of the ampulla of vater
liver disease
40

liver metastasis
Are you guessing at these or looking up the labs?
42
A 54 year old man undergoes a laparoscopic cholecystectomy for symptomatic gallstone disease. The surgery is uneventful but 2 days after the procedure the patient develops intense abdominal pain. His bilirubin and aspartat transaminases (AST) are elevated. There is no fever. The lipase is normal. What is the most likely cause of this patient's symptoms?
A) bile leak
B) pancreatitis
C) post-operative infection
D) retained stone
retained stone
This patient most likely has a retained stone in the bile duct. It may have escaped the GB during surgery and now is in teh duct.
No fever rules out infection.
Normal lipase rules out pancreatitis
Bile leaks do not affect AST
The rise in bilirubin along with AST is consistent with obstruction of the CBD
43
All of the following may contribute to or cause primary sclerosing cholangitis except:
A) ulcerative colitis
B) autoimmune disorders
C) chronic pancreatitis
D) bilomas
bilomas
44
Hydrops of the gallbladder is
an enlarged gallbladder
Hydrops is dilatation of the gallbladder which is often caused by an obstruction of the cystic duct. It is important to remember this because you must FIND the stone in the cystic duct, and we normally do not see or image the cystic duct. Often the stone may be seen between the gallbladder and the common hepatic duct, but the cystic duct itself is not seen. Sonographers who do not make a conscious effort to look for this stone often miss it.
45
