恶性非霍奇金淋巴瘤容易累及中枢神经系统,绝大多数为原发性,极少数为继发,其中多数为弥散大B细胞淋巴瘤,常常位置较深、多中心起源及弥漫浸润周围脑组织[1]。近年来,无论是在免疫正常者还是免疫缺陷者中,原发性中枢神经淋巴瘤的发病率均逐渐增加[2]。且由于术前大量激素的应用,往往使病理诊断更加困难。原发性中枢神经淋巴瘤在影像学上具有一定特征,以往文献虽多有报道,但大多正确诊断率不高,而正确的影像学诊断对于临床活检及治疗方法的
Malignant non-Hodgkin’s lymphoma easily affects the central nervous system, the vast majority of primary, very few secondary, most of them diffuse large B cell lymphoma, often deep, polycentric origin and diffuse infiltration of the surrounding brain Organization [1]. In recent years, the incidence of primary CNL lymphoma has gradually increased in both immunocompromised and immunocompromised patients [2]. And because of the large number of hormones before surgery, often makes the pathological diagnosis more difficult. Primary CNL lymphoma has some features in imaging. Although many reports have been reported in the past, most of them are not correctly diagnosed. However, the correct imaging diagnosis is of great value to clinical biopsy and treatment
