Abstract
Acalculous cholecystitis is thought to occur in patients with a severe systemic illness or during long periods of intravenous nutrition. We discuss a case of acalculous cholecystitis secondary to Epstein-Barr virus detected by bedside ultrasound. We hope to alert clinicians who are actively using bedside ultrasound of an important, yet not commonly discussed, association. [West J Emerg Med. 2011;12(4):
