Abstract

Orbital pseudotumor, also known as idiopathic orbital inflammatory syndrome(IOIS), may have protean clinical manifestations. IOIS should be determined with a diagnosis of exclusion, with evaluation directed toward eliminating other causes of orbital disease. Orbital MRI and CT are the important diagnostic tests, but serologic studies are necessary to exclude a systemic causes. Biopsy is usually not performed currently, as the risk of producing damage to vital structures within the orbital outweighs the benefits. Patients with multiple recurrences, or those unresponsive to therapy, should be treated of biopsy sample extraction. Corticosteroids are the mainstay of therapy and administered for several months to ensure remission. Radiotherapy may be used in patients who fail to respond to steroids or who have a rapidly progressive course. We analysed the data of two patients. There were no specific complications related to this treatment. We discussed the radiologic findings, treatment procedures, and other orbital diseases.
