Abstract
A seven-month-old Italian greyhound with bilateral exophthalmos was diagnosed with immune-mediated extraocular myositis (EOM) according to results of neurological, magnetic resonance imaging (MRI) and serological examinations. A histpathological view from a biopsy has been considered necessary for a definitive diagnosis of inflammatory myopathies. In this report, the authors also identified MRI findings, such as enlargement and marked contrast enhancement of extraocular muscles, along with the presence of an IgG autoantibody in the serum. We can apply these findings to EOM diagnosis.
