原发性中枢神经系统恶性淋巴瘤临床和影像学特点分析

目的：分析中枢神经系统淋巴瘤的临床表现、影像学特点并探讨其治疗方法。方法：对28例原发于中枢神经系统的恶性淋巴瘤进行回顾性分析。结果：28例淋巴瘤全部经手术及病理证实。术后生存期5 d~40月。术后18例患者接受放疗。经影像学证实的术后复发共16例。其中最短复发时间为术后第29 d。结论：中枢神经系统淋巴瘤病史短、临床症状重，影像学有一定的特征性改变；即使于显微镜下全切除，也可于术后短期内复发。大多数淋巴瘤对放疗敏感。

Clinical and neuroimage characteristics of primary central nervous system lymphoma

Objective To analyze the clinical and neuroimage characteristics of primary central nervous system lymphoma and explore the methods of treatment. Methods The clinical data of 28 cases of primary central nervous system lymphoma were analyzed retrospectively. Results All the 28 patients with lyphoma were proved by craniotomy and pathologic study. The survival periods were 5 days to 40 months after the craniotomy.Eighteen patients received radiotherapy after the operation.Sixteen recurrent cases were proved by neuroimage and the minimum recurrent time was the 29th day after the operation. Conclusion The duration of primary lymphoma in the central nervous system is short and the clinical symptom is serious . The neuroimage of primary lymphoma in the central nervous system has some characteristic changes .The recurrence may occur over a brief time after the operation even though the tumor has been totally removed under the microscope.The majority of lymphomas are sensitive to radiotherapy.
