Diverticular abscess presenting as prostate abscess and missed by abdominal CT scan

Abstract 

This is a case report of sigmoid diverticular abscess presenting as prostate abscess. Helical computed tomography (CT) scan revealed the prostate abscess but failed to demonstrate the underlying diverticular abscess. Colonic diverticular abscess can have many unusual presentations, and multiple imaging modalities may be required to reveal the underlying pathology. Abdominal CT scan is not always a definitive and absolute imaging modality for abdominal pain evaluation and cannot supplant clinical judgment in the evaluation of confusing cases.
