Acute biliary tract disease associated with echovirus 11 infection

A patient hospitalized with the clinical diagnosis of acute cholecystitis had a normal cholangiogram and recovered without medical or surgical intervention. During the same week, two adults in an acquainted family had a similar syndrome at home. Echovirus 11 was cultured from the stool of all three patients, as well as from four other members of the same two families who had concurrent diarrheal illness. Serologic evidence confirmed acute echovirus 11 infection in the hospitalized patient. In the absence of evidence of a communitywide epidemic of cholecystitis, the coexistence of viral infection with biliary tract symptoms could represent an ongoing endemic situation. Recognition of this syndrome could make it possible to avoid unnecessary major surgical procedures.
