Title: An Unusual Differential Diagnosis of Orbital Cavernous Hemangioma: Ancient Schwannoma.
Issue Date: May-2017

Abstract: Schwannomas are rare lesions of the orbit that can be confused with cavernous hemangioma on imaging studies. We report the case of an 84-year-old woman with a 9-year history of a tumoral lesion in the inferolateral left orbit. The imaging studies did not reveal specific characteristics, only bone remodeling due to the long evolution of the tumor. The patient underwent complete excision of the tumor by anterior orbitotomy via the inferior conjunctival fornix. The histopathological examination revealed an ancient schwannoma, a variant of schwannoma with uncommon histological features. The follow-up was uneventful. The present case emphasizes the importance of considering neural tumors in the differential diagnosis of orbital masses with bone changes and degenerative alterations such as hemorrhagic areas, cysts, and/or calcifications.
