Small bowel diverticulitis: an often overlooked cause of acute abdomen.

We present 3 cases of small bowel diverticulitis ultimately presenting to our Emergency Department over a span of 2 years. Though the final diagnosis was the same, each patient's symptomatology was different, mimicking more common pathologies. Thus, it is important to consider this entity when confronted with signs and symptoms of acute abdomen, especially in the elderly. A missed or delayed diagnosis can lead to costly erroneous studies, incorrect treatments and delay in proper management, resulting in significant morbidity and even mortality. The variety of presentations can often be misleading; therefore, a high index of suspicion is needed on the part of the Emergency Department physician and Radiologist.
