The features of gliomatosis cerebri involving the brainstem and cerebellum in a 3‐year‐old dog are described. In magnetic resonance ( MR ) images, there was diffuse loss of the cerebellar folia and cerebellar gray and white matter contrast. Multiple illdefined T 2‐hyperintensities were present in the cerebellar parenchyma. A poorly defined, T 2‐hyperintense mass effect was present ventral to the pons and rostral medulla. No contrast enhancement was noted. Cerebrospinal fluid ( CSF ) was normal. Postmortem examination was consistent with gliomatosis cerebri, based on compatible histopathology and immunohistochemical findings. Although rare, gliomatosis cerebri should be included as a differential for diffuse infiltrative central nervous system ( CNS ) lesions.
