Orbital lymphomas: clinical and radiological features.

The purpose of this prospective study was to evaluate the clinical and radiological features of a consecutive series of orbital lymphomas in two Institutions in the North West of Italy. A prospective study was performed of all cases of diagnosed orbital lymphomas. Data on patient demographics, symptoms and clinical findings, histological type of lymphoma, site of lesion, imaging, and systemic involvement were recorded in each case. The mean age of the enrolled 20 patients was 63.65 years. Most orbital lymphomas were located in the superior-lateral quadrant. Superior rectus muscle was the most frequently involved orbital structure. Most patients were affected by extranodal marginal-zone lymphomas. The diagnosis of orbital lymphomas may be challenging, because these neoplasms present few specific features. Although not typically performed by the maxillofacial surgeon, an understanding of the staging process is crucial for multidisciplinary management of orbital lymphomas.
