Gemistocytic astrocytoma in a one-month-old llama.

Abstract

A tumor involving the caudal portion of the brainstem was detected at necropsy after euthanasia of a 1-month-old llama with clinical signs consistent with vestibular disease. Gemistocytic astrocytoma of the medullary mass was the histopathologic diagnosis. Regardless of age, neoplasia should be included in differential diagnosis in animals with signs referable to the CNS.
