A boa constrictor was submitted for postmortem evaluation. At necropsy, there were no substantial lesions except in the liver. Light microscopy revealed severe multifocal to coalescing coagulative necrotic hepatitis, with basophilic and eosinophilic intranuclear inclusions in hepatocytes within the necrotic foci. The histopathological findings suggested a viral hepatitis. An adenoviral infection was diagnosed by means of transmission electronic microscopy and in situ hybridization techniques.
