What combination of findings on ultrasound typically confirms a diagnosis of cholecystitis?

• A. GB wall thickening >4mm, pericholecystic fluid, gallstone
• B. Dense liver, absent gallstones, normal GB wall
• C. Only GB wall thickening
• D. Gallstones and hepatic steatosis

Answer: (A)

The correct answer highlights key ultrasound findings that are indicative of cholecystitis, which is inflammation of the gallbladder. The combination of gallbladder (GB) wall thickening greater than 4mm, the presence of pericholecystic fluid, and the visualization of gallstones is significant.

Thickening of the gallbladder wall is often a response to inflammation and infection. The measurement of greater than 4mm serves as a threshold that suggests a pathologic process. Pericholecystic fluid, which is fluid accumulation around the gallbladder, is another critical sign that indicates infection and can occur due to a rupture or significant inflammation. Finally, the presence of gallstones (cholelithiasis) serves to further support the diagnosis, as these stones can obstruct the cystic duct, leading to the inflammation seen in acute cholecystitis.

Together, these three findings create a strong clinical picture for confirming cholecystitis via ultrasound, making this combination the correct option in diagnosing the condition accurately. Other options lack the necessary features that would substantiate a diagnosis of cholecystitis effectively.
