Objectives: After studying the article entitled “Emphysematous Cholecystitis: A Deadly Twist to a Common Disease,” you will be able to:
Discuss the etiologies of emphysematous cholecystitis
Correlate clinical presentation with sonographic findings
Differentiate acute cholecystitis from emphysematous cholecystitis
Which one is not a theorized etiology of emphysematous cholecystitis? Incompetent sphincter of Oddi Transhepatic arterial embolization Adenomyomatosis Acute cholecystitis
In comparison of acute cholecystitis and emphysematous, in acute cholecystitis, there is higher risk of which of the following? Gallstones Gangrene Perforation Mortality
Which laboratory value is elevated in EC but not as much if any in acute cholecystitis? Leukocytes Serum glucose Amylase Alkaline phosphatase
The primary concern for a sequela for EC is Gangrene sets into the wall of gallbladder Diabetes neuropathy Perforation of gallbladder Altered immunity
The “champagne” sign refers to a(n) Comet tail artifact emanating from the wall Anechoic crescent-shaped fluid collection Wide band of acoustic shadowing from gallbladder wall Echogenic foci rising in the gallbladder lumen
A key sonographic differentiation between EC and acute cholecystitis is that EC will demonstrate Pericholecystic fluid Gas in gallbladder wall Enlarged cystic artery Gallbladder wall thickening
Differentiation between adenomyomatosis and EC can be made by which artifact? Acoustic shadowing Acoustic enhancement Linear-shaped dirty shadow U-shaped comet tail
Which imaging examination yields the highest sensitivity for diagnosing EC? Computed tomography MRI Plain abdominal radiograph Sonography
Which imaging modality displays a pear-shaped lucency in the RUQ in cases of EC? Computed tomography MRI Plain abdominal radiograph Sonography
Which one is not a treatment option for EC? Hyperbaric oxygen therapy Cholecystectomy Percutaneous drainage of gallbladder Anti-inflammatory medications
