Abstract
We report a 50-year-old woman with orbital sarcoidosis. The initial presentation was painless swelling in the upper eyelid and mildly limited extraocular motion. A heterogeneous mass with a surrounding bony defect was noted on an orbital computerized tomography scan. Histopathological examination revealed noncaseating granulomas, which were compatible with a diagnosis of sarcoidosis. Elevation of the serum angiotensin-converting enzyme level and mediastinal lymphadenopathy, found on chest computerized tomography, also confirmed the diagnosis. The patient was treated with low-dose corticosteroids for 5 weeks and showed a favorable outcome.
