MR imaging data were reviewed retrospectively in four male patients (32 to 74 years old) with histologically confirmed intravascular lymphomatosis (IVL), a rare, aggressive form of non-Hodgkin lymphoma. MR findings included infarct-like lesions (n = 2), focal parenchymal enhancement (n = 3), dural/arachnoid enhancement (n = 2), and, in one case, nonspecific, patchy foci of increased signal in the white matter on long-TR images. All patients had multifocal lesions. Knowledge of the spectrum of MR imaging features in this unusual disorder may aid in diagnosis and potentially enhance the role of imaging in following response to therapy.
对4例男性患者（年龄32至74岁）的磁共振成像（MR）数据进行了回顾性分析，这些患者经组织学证实患有血管内淋巴瘤（IVL），这是一种罕见的侵袭性非霍奇金淋巴瘤。MR表现包括梗死样病变（n = 2）、局灶性实质强化（n = 3）、硬脑膜/蛛网膜强化（n = 2），并且在1例患者中，在长TR图像上白质出现非特异性斑片状高信号灶。所有患者均有多灶性病变。了解这种罕见疾病的MR成像特征谱可能有助于诊断，并有可能增强成像在监测治疗反应中的作用。
