原发性脑淋巴瘤的CT 、MRI 影像学特征Comparative study of CT and MRI manifestations and pathologic findings of primary brain lymphoma 摘要 : 目的：探究原发性脑淋巴瘤的的CT、MRI特征。方法 : 选取 2015 年 6 月-2016年 6 月期间我院收治30 例原发性脑淋巴患者作为研究对象，分析患者CT、MRI特征。 结果： 影像学方面， CT 扫描显示肿瘤细胞成像较整齐，常见一些等密度甚至是高密度的肿块； MRI扫描结果显示影像上没有明显的边界，边界比较模糊；本次研究的 30 例患者中，多发肿瘤、单发肿瘤分别为26 例、 32 例，病灶总计58 个；肿瘤体积大小11mm×14mm～45mm×66mm；从水肿方面分析，轻度水肿、中度水肿例数都是15 例，重度水肿 10 例，无水肿 18 例；呈团块样为 32 个，握拳样为 16 个，尖突状为 10 个。结论： 原发性脑淋巴瘤在CT、MRI表现中具有一定的特异性，进而结合病灶的分布特点、信号特征、形态特点等多方面特点，提高临床诊断效果。Abstract: objective: to explore the CT and MRI features of primary brain lymphoma. Methods: to choose in June 2015 - June 2016 our hospital during the period of 30 patients with primary cerebral lymphatic as the research object, analysis of patients with CT and MRI features. Results: imaging, CT scan revealed a tumor cell imaging is neat, even high density mass density such as common; MRI scan results show that there is no obvious image boundary, boundary is vague; The study of 30 cases, multiple tumors, single tumor of 26 cases respectively, 32 cases, a total of 58 lesions; Tumor size 11 mm x 14 mm ~ 45 mm * 66 mm; Analysis from the aspects of edema, mild edema, moderate edema, the number of cases is 15 cases, 10 cases of severe edema, no edema, 18 cases；A mass sample for 32, clench fist sample for 16, pointed protrusions to 10. Conclusion: primary brain lymphoma in CT, MRI manifestation of specificity, and combining with the characteristics of the distribution of the...
