Which abnormal findings on an abdominal CT scan require immediate reporting to the provider?

Bowel obstruction and acute pancreatitis are critical findings on an abdominal CT scan that necessitate immediate reporting to the provider because they can lead to severe complications if not promptly addressed.

Bowel obstruction may result in bowel ischemia, perforation, or infection, all of which can rapidly deteriorate the patient's condition and require urgent surgical intervention. Acute pancreatitis, particularly if severe, can lead to systemic complications like organ failure or necrotizing pancreatitis, both of which demand immediate medical attention and potential hospitalization.

The other conditions mentioned, while they may require further evaluation or management, do not typically represent emergencies. For instance, gallstones and renal cysts, inflammation and diverticulosis, as well as liver lesions and lymphadenopathy, can often be managed through outpatient treatment or scheduled follow-up rather than requiring immediate intervention.
