Orbital masses are often challenging for radiologists due to their variable imaging appearance and their multiple etiologies.
Possible etiologies include benign and malignant neoplasms,
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.
final diagnosis will require also a MRI study due to its high soft tissue contrast and spatial resolution.
