ABSTRACT

 

Da Silva EO, Ferioli RB, Moreno K,  Bracarense AP., Case Study: Feline spinal cord gemistocytic astrocytoma, Onl J Vet Res, 15 (3): 200-210, 2011.  Primary spinal cord tumors are rare in cats. A six-year-old, intact male Siamese cat had a history of progressive hemiparesia, muscle atrophy in the right thoracic limb and regional pain. Neurological exam revealed increased reflexes, hyperesthesia and propioceptive deficit in the right thoracic limb. Medical therapy was initiated, but neurological signs were progressive and severe, affecting the pelvic limbs. The owner opted for euthanasia. Gross exam showed a swollen area in the C6 region of the spinal cord. Histopathological examination showed diffuse proliferation of large cells with abundant eosinophilic cytoplasm and eccentrically located large nuclei with prominent 8positive staining for S100, vimentin and GFAP (glial fibrillar acid protein) and negative staining for macrophage antigens (lysozyme and LN-5). Based on histopathological and immunohistochemical features, a diagnosis of gemistocytic astrocytoma was made.
