Unilateral internal and external ophthalmoplegia caused by an intracranial meningioma occurred in a 15-year-old Belgian Sheepdog. The dog initially presented with ventro-lateral strabismus of the left eye, and ptosis of the left upper eyelid. Anisocoria was present with the left pupil fixed and dilated. Both eyes were visual. Neuro-ophthalmic evaluation revealed a lesion located in the left oculomotor nerve. Pharmacological testing with dilute pilocarpine (0.1% in artificial tears) revealed evidence of parasympathetic denervation of the left eye. Further evaluation via magnetic resonance imaging (MRI) revealed a well-defined mass to the left of midline and lateral to the sella turcica. An attempt was made to excise/debulk the mass due to worsening conditions and the dog died the following day. Necropsy revealed a mass of randomly arranged bundles and streams of spindle cells. Immunohistochemistry demonstrated a strong avidity for vimentin and a negative response for S-100 protein. These findings suggest a diagnosis of meningioma.
