眼眶淋巴瘤的CT诊断

CT diagnosis of orbital lymphoma

目的:探讨眼眶淋巴瘤的CT表现,提高对其诊断鉴别能力。方法:回顾性分析经手术病理证实的12例眼眶淋巴瘤的CT表现,并作文献复习。结果:12例淋巴瘤中仅1例为霍奇金淋巴瘤,病变位于右侧眼眶肌锥内间隙。11例为非霍奇金淋巴瘤,双侧眼眶发病1例,其余为单侧。12例中局限型7例,病变局限于眼球周围,弥漫型5例,表现为肌锥内外间隙弥漫软组织影,沿眶锥“铸形”生长。结论:淋巴瘤的CT表现具有一定的特征性,即眼眶内软组织包绕眼球生长,眼环无增厚及凹陷,是提示淋巴瘤的重要线索。但最后的诊断有赖于病理活检及免疫组化。

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.
