Orbital masses are often challenging for radiologists due to their variable imaging appearance and their multiple etiologies. Possible etiologies include benign and malignant neoplasms, vascular lesions, congenital lesions, inflammatory-infectious lesions and miscellanous etiologies. Biopsy requires highly experienced surgeons and is not exempt of morbidity for the patient. Imaging has a major role in the diagnosis process. Radiologists must be aware of key imaging features that may help to differentiate benign and malignant lesions and give a diagnostic approach. CT is the first imaging modality to evaluate orbital masses in emergency departments. Nonetheless, final diagnosis will require also a MRI study due to its high soft tissue contrast and spatial resolution.
