We report a case of orbital myositis revealed by a relapsing and initally painless ophthalmoplegia. Case report. A 50-year-old patient suddenl y presented with an isolated palsy of the right lateral rectus muscle which reco vered in 3 weeks after a short-lasting corticosteroid therapy but relapsed. Cer ebral and orbital imaging were normal. Orbital pain with a fluctuating course oc curred 6 months later. Two years after the clinical onset, orbital CT scan revea led a fusiform hypertrophy of the right lateral rectus muscle which was enhanced by contrast.After corticosteroid treatment, the symptoms improved and CT scan b ecame normal. Conclusion. Orbital myositis may not be ruled out in case of painl ess ophthalmoplegia and systematic and repeated imaging is necessary.展开更多
