Diagnosis of orbital diseases is made clinicoradiological and confirmed on histopathological and immunohistochemical studies. The recent advances in orbital imaging allow the clinician to identify not only the location of the lesion and its relation to adjacent structures, these are: (i) Computerized tomographic scanning (CT Scan): CT scan provides good visualization of all orbital tissue and surrounding bones. Intravenously administered contrast medium increases the visualization and suggests the vascularity of the lesion. (ii) Magnetic resonance imaging (MRI): Magnetic resonance imaging provides images of the orbital soft tissue in equal or slightly better detail than CT scan. Bony details and calcifications are not well visualized with this technique. (iii) Ultrasonography (USG): USG are the radiological tools. Standardized echography includes A-scan, B-scan and Doppler echography. Information obtained from ultrasonography of the orbit includes size and shape of the lesion, borders, and tissue composition (cystic or solid). Ultrasonography is used primarily as an adjunctive imaging modality. These tests are complementary to each other and are not mutually exclusive.
