Orbital lesions including inflammatory pathologies and tumors pose numerous challenges in terms of diagnosis due to similar clinical presentation. Schematically, orbital tumors can be divide into (1) primary lesions which originate from orbit and its contents ( globe, muscles, fat, vessels, nerve ) itself, (2) secondary lesions which extend into orbit from adjacent structures and (3) metastatic lesions. The computed tomographic features of the following intraconal and extraconal space occupying lesions would be discussed – Retinoblastoma, Rhabdomyosarcoma, Hemangioma, Mucocele, Orbital Varix, Meningioma and Orbital abscess. Recognition and early detection of these lesions is essential for treatment for which high resolution imaging studies provides invaluable information regarding possible origin and extent of lesion.
