Abstract
Purpose
To report a case of complete oculomotor nerve palsy with pupil involvement complicated by inflammation of the cav-ernous sinus. Complete resolution was obtained after 12 days of antiviral and steroid treatments.
Case summary
A 60-year-old male presented with edema and vesicles of the right upper eyelid. The patient had myalgia, cough, fever and headache 1 week earlier and was treated with conservative therapy. The patient received an antiviral agent (famciclovir 250 mg) twice a day and steroid agent (methylprednisolon 4 mg) once a day at the dermatology department for 1 week. The eyelid edema and vesicles improved. However, ptosis, ocular movement limitation, mydriasis of the right eye and dip-lopia occurred. Brain magnetic resonance imaging revealed hyperintensity in the right cavernous sinus with enhancement, im-plicating inflammation. The patient was diagnosed with right complete oculomotor nerve palsy with pupil involvement. An anti-viral agent (famciclovir 250 mg) three times a day and a steroid agent (prednisolone 40 mg) once a day were prescribed. From the next day, ptosis and ocular movement limitation improved and 12 days later, completely resolved.
