No - not diverticular disease.

The patient did have diverticular disease, but then diverticula are quite common in otherwise healthy people and are often an incidental finding at autopsy. In this case, one of the diverticula seems to have become acutely inflamed... think about the site of the patient's diverticular disease, then think about the name of the bacterium grown in the blood culture.

Put two and two together, then try again
