Probably this patient suffers of an acute diverticulitis.
Is it an urgent imaging necessary to confirm the diagnosis?
The patient presented above has a high probability to have an acute non complicated diverticulitis, imaging tests have a little impact on disease’s management.
Imaging is necessary when all 3 clinical features aren’t present, or when the patient is very ill and the suspect of any complication is very high.
On the other hand the absence of any of 3 clinical features isn’t useful to rule out an acute diverticulitis.
A clinical decision rule to establish the diagnosis of acute diverticulitis at the Emergency Department.
