Abstract：Objective: This article explores how to diagnose lymphoma in the orbit by CT in order to improve the ability of diagnosing. Methods: In this paper, the CT features of orbital lymphoma in 12 cases proved by operating pathology were analyzed retrospectively. Results: In these 12 cases, only 1 is Hodgkin’s disease, whose pathological changes are in extraconal compartment, and the other 11 are non-Hodgkin’s lymphoma, in which merely one involved both eyes, and others on one side. Seven are of confined-type whose pathological changes exist around the eyes, and 5 are of diffused type, on whose picture there are shapes of soft-tissue in extraconal orbital compartment. Conclusion: Lymphoma has certain features on CT. The important clue of lymphoma is that the soft-tissue mass grows around the eye ring. But the final decision is made according to biopsy and immunohistochemistry.
