title: Orbital inflammatory syndrome: an unusual presentation.
abstract: A 22-year-old woman had right unilateral proptosis. Evaluation revealed a large intraconal orbital mass, consistent with cavernous hemangioma. The mass was removed via a lateral orbitotomy. Histopathology, confirmed by electron microscopy, demonstrated fibroblasts with inflammatory histiocytes, but there was no evidence of cavernous hemangioma. To our knowledge, this is the first description of a well-circumscribed intraconal mass diagnosed as orbital inflammatory syndrome.
