Progression of which of the following abnormalities flattens the portal veins? -
ANSWER Biliary obstruction
The wall thickness in a normal fasting
... [Show More] gallbladder should not exceed -
ANSWER 3 mm
This color Doppler sonogram is most likely demonstrating which of the
following abnormalities? - ANSWER Pseudoaneurysm
This color Doppler image demonstrates turbulent swirling blood flow within a
fluid collection, classic sonographic findings of a common femoral artery
pseudoaneurysm.
A patient presents with sudden onset of upper abdominal pain. Ultrasound
demonstrates prominence in the stomach rugae. These findings are most
suspicious for which of the following conditions? - ANSWER Gastritis
Prominence of the stomach rugae in a patient with upper abdominal pain is
most suspicious for gastritis. Hypervascular, thick gastric walls are
sonographic findings associated with gastric ulcers.
Which of the following is a complication of acute pancreatitis? - ANSWER
Duodenal obstruction
Complications of acute pancreatitis may include abscess formation, duodenal
obstruction, hemorrhage, phlegmon, and pseudocyst formation. Cholecystitis
is a possible etiology of acute pancreatitis.
A patient presents with a history of hematuria. The findings in this duplex
image are most suspicious for which of the following pathologies? - ANSWER
Carcinoma
A vascular echogenic mass is identified protruding from the posterior wall of
the urinary bladder. Bladder carcinoma commonly presents with a history of
painless hematuria. Based on the clinical history, the sonographic findings are
suspicious for a malignant mass.
A sagittal sonogram medial to the porta hepatis is demonstrating which of the
following abnormalities? - ANSWER Dilated common bile duct
A hypoechoic mass identified by the calipers is obstructing the common bile
duct resulting in dilatation. The mass is most likely a malignancy in the head of
the pancreas.
The pathology in this sonogram is most likely a/an - ANSWER Pseudocyst
A complex fluid collection is identified posterior to the tail of the pancreas.
This is most likely a pancreatic pseudocyst. Phlegmons and islet cell tumors
appear as hypoechoic masses on ultrasound. A pancreatic hemorrhage is a
differential consideration but not the most likely pathology. [Show Less]
