Abstract

Intraorbital pseudotumors are inflammatory lesions of the orbit of unknown etiology, which initially mimic an orbital neoplasm. The authors report a case of intraorbital pseudotumor presenting with painful exophthalmos. A 45-year-old male patient had a two-week history of acute progressive exophthalmos and diplopia. Right orbit was explored through transcranial route and the mass was biopsied, which revealed dense inflammatory cells and fibrosis. He subsequently underwent corticosteroid therapy and symptoms improved gradually. The literatures were reviewed.
