Homogenous eosinophilic intracytoplasmic inclusion bodies were found within the large reticular neurons of the brain stems of 57 captive woodchucks (Marmota monax). Light microscopy was consistent with a proteinaceous nature, while electron microscopy suggested a non-viral origin. The woodchucks with inclusions were older than the general population that was studied. It is hypothesized that the neuronal inclusions in the brain stem are indicative of nonspecific ageing changes.
