| Popis: | A 14-month-old female pitbull terrier mix was presented for evaluation of dysphagia of 8 months' duration secondary to intermittent dorsiflexion of the tongue apex. Physical and neurological examinations were unremarkable with the exception of the dorsiflexed tongue. Serum creatine kinase activity was increased (703 IU/L, reference interval: 55 to 257 IU/L), and electromyography of the tongue demonstrated areas of fibrillation potentials. Histopathology of the tongue showed myopathic changes with excessive variability in myofibre size and endomysial fibrosis. Cytochemical stains verified mixed mononuclear cells throughout the endomysium and perimysium consistent with a chronic inflammatory myopathy. No improvement was reported following prednisone administration; although the dog was able to prehend kibble, it needed assistance when drinking water. This is the first report documenting a focal lingual myopathy in a non-corgi breed and highlights the utility of determining creatine kinase activity and obtaining tongue biopsies when warranted in dysphagic animals. |
