What should the impression contain for a CT abdomen with contrast when appendicitis is suspected?

• A. Provide a concise impression such as 'Appendicitis suspected' with supporting imaging findings (e.g., enlarged appendix, periappendiceal fat stranding) and recommend clinical correlation and possible surgery referral.
• B. Report that the appendix is normal and appendicitis is unlikely without supporting features.
• C. Recommend MRI abdomen to confirm diagnosis.
• D. State that imaging shows no acute abdominal pathology.

Answer: (C)

The main idea is to give an impression that directly answers the clinical question with imaging evidence. When appendicitis is suspected on a CT abdomen with contrast, the impression should be concise and clearly state whether appendicitis is suspected or not, based on concrete imaging findings, and it should point to the next steps in management. If the CT shows signs supporting appendicitis—such as an enlarged appendix (diameter typically >6 mm), wall thickening or enhancement, periappendiceal fat stranding, possible appendicolith, and perhaps small amount of periappendiceal fluid—the impression should summarize these findings and conclude that appendicitis is suspected. It should also include guidance for management, commonly a note for clinical correlation and a possible surgical referral, since definitive treatment would usually be surgical. If there are no imaging features of appendicitis and no supportive signs, the impression should reflect that, and it should acknowledge the differential diagnosis and discuss potential next steps if symptoms persist. It’s not appropriate to default to a statement of no acute pathology when there is ongoing clinical concern, and this is why simply ruling out appendicitis without context isn’t ideal. Recommending an MRI after a CT to confirm the diagnosis isn’t standard practice in the typical workup of suspected appendicitis. CT with contrast is usually the definitive or highly informative test, and MRI is reserved for special situations (such as pregnancy, radiation concerns, or nondiagnostic CT), rather than being a routine next-step directive in the impression. So, the best impression approach is a concise, imaging-based conclusion about appendicitis with key supportive findings and a note about clinical correlation and potential surgical referral, rather than directing that an MRI should be obtained.
