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.

We describe the case of a male patient who presented with anisocoria, and was initially diagnosed with an acute Adie's tonic pupil. On subsequent laboratory testing, he was found to have neurosyphilis. Magnetic resonance imaging demonstrated enhancement of the right oculomotor nerve. This case underscores the importance of considering this diagnosis in patients with acute onset internal ophthalmoplegia and hypersensitivity to dilute pilocarpine, even in the absence of other oculomotor nerve findings.

Isolated bilateral internal ophthalmoplegia is a rare and problematic condition affecting activities of daily living. Herein, we describe the cases of 2 patients with postinfectious isolated bilateral internal ophthalmoplegia, i.e., mydriasis without external ophthalmoplegia. One patient demonstrated no other neurological symptom, while the other patient showed mild gait ataxia. Magnetic resonance imaging revealed no abnormal findings in the brain or brainstem. Light-near dissociation of the pupils was not recognized in either patient, and supersensitivity to dilute pilocarpine was observed in 1 of the 2 patients. An increased titer of the anti-GQ1b IgG antibody was noted in 1 patient. A review of the literature revealed five similar cases; the symptomatic characteristics, ratio of positive anti-GQ1b IgG antibody, and effective treatment are discussed.
