title: 'Ring' granulomas in cytomegalovirus hepatitis.
abstract: A liver biopsy specimen obtained from a patient with cytomegalovirus hepatitis demonstrated "ring" granulomas similar to those previously described as characteristic of acute Coxiella burnetii infection. Q fever is not the only infectious disease in which fibrinoid rings may form within granulomatous foci.
