The patient was a 51-year-old man who complained of subacute diplopia and developed right eyelid ptosis one month later. Thyroid-associated ophthalmopathy（TAO）due to hyperthyroidism associated with myasthenia gravis（MG）was suspected based on a blood test and MRI. Methylprednisolone pulse therapy improved diplopia; however, right eyelid ptosis and the eye movement disorder persisted. After the second pulse therapy, improvement of the right eyelid ptosis was observed; however, limited eye movement fluctuated daily. It was difficult to accurately determine which disease was predominant and how effective treatment was for TAO and MG. However, it may be possible to evaluate the degree of improvement using characteristics and MRI findings.
