目的:分析原发性中枢神经系统淋巴瘤CT诊断的临床价值。方法:选取2007年12月—2010年12月我院收治的原发性中枢神经系统淋巴瘤患者40例,男26例,女14例,使用Sytec-Synergy螺旋CT诊断。结果:40例平扫均为多发结节状略高密度影,其中2例幕上白质内和幕下小脑半球发现多发结节灶,最少4个,最多9个,相对较均匀,大小在0.7～1.2cm之间,形状为圆形或椭圆形,其周围水肿区均不十分明显,占位效应为病灶多的一侧明显,仅1例。增强扫描后,其中16例病灶明显强化,4例中度强化。结论:CT可发现较大的规则团块影,呈高密度或等密度,增强效应明显,室管膜下浸润时脑室周围增强。
Objective: To analyze the clinical value of CT diagnosis of primary central nervous system lymphoma. Methods: Forty patients with primary central nervous system lymphoma, including 26 males and 14 females, who were admitted to our hospital from December 2007 to December 2010, were diagnosed by Sytec-Synergy spiral CT. Results: In 40 cases, multiple nodules were slightly elevated. Among them, 2 cases showed multiple nodules in the white matter and the infratentorial cerebellar hemispheres, at least 4, at most 9, and relatively uniform with a size of 0.7 ~ 1.2cm between the shape of a round or oval, the surrounding edema area are not very clear, placeholder effect for the side of the lesion more obvious, only 1 case. After enhanced scan, 16 lesions were significantly enhanced, 4 moderately enhanced. Conclusion: CT can be found larger rules of the mass shadow, was high density or isodense density, enhancement effect was obvious, subependymal infiltration around the ventricle increased.
