Description
Summary:A case of fibroblastic meningioma is reported in a bovine, presenting depression, purulent nasal discharge, bruxism, eyelid ptosis, tongue paralysis, and trismus. At necropsy there was a tumor in the region of the right frontal cortex, occupying the right lateral ventricle. Microscopically it was composed by neoplastic meningothelial cells. The diagnosis was performed based on histologic characteristics and confirmed by immunohistochemistry revealing that tumor cells were positive for vimentin and negative to cytokeratin, glial fibrillary acidic protein, and neuron specific enolase. Diseases of the central nervous system are important in cattle in the semiarid region of northeastern Brazil, and tumors of the brain and spinal cord should be included in the differential diagnosis of this group of diseases.
