Features suggestive of Acute cholecystitis on CT abdomen are all Except
**Core Concept**
Acute cholecystitis is a condition characterized by inflammation of the gallbladder, often resulting from gallstones obstructing the cystic duct. This leads to gallbladder distension, ischemia, and subsequent inflammation.
**Why the Correct Answer is Right**
The features suggestive of acute cholecystitis on CT abdomen include gallbladder distension, wall thickening, pericholecystic fat stranding, and the presence of a gallstone in the cystic duct or gallbladder. These findings are a result of the inflammatory process and the subsequent ischemia caused by the obstruction. The gallbladder's position and relationship to surrounding structures, such as the duodenum and colon, can also be affected.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify a feature of acute cholecystitis. Without further information, it's difficult to determine its relevance.
**Option B:** This option is incorrect as it may be a feature of other conditions such as pancreatitis or a tumor, rather than specifically acute cholecystitis.
**Option C:** This option is incorrect as it is actually a feature of acute cholecystitis. The presence of a gallstone is a common cause of the condition.
**Clinical Pearl / High-Yield Fact**
When interpreting CT scans of the abdomen, it's essential to remember that gallbladder wall thickening and pericholecystic fat stranding can be early signs of acute cholecystitis. These findings can precede the more obvious gallbladder distension and may aid in the diagnosis of this condition.
**Correct Answer: C. The presence of a gallstone is a common cause of the condition.**
