摘要
目的提高对肝淋巴瘤CT表现的认识。方法回顾性分析经病理或相关临床资料证实的11例肝淋巴瘤的CT表现,原发性肝淋巴瘤1例,继发性肝淋巴瘤10例,采用螺旋CT平扫与增强(动脉期及实质期)检查。结果1例原发性肝淋巴瘤,CT平扫表现为肝内单发稍低密度肿块,增强扫描无明显强化;10例继发性肝淋巴瘤,1例为单发肿块,9例为肝内多发结节或肿块。所有病例平扫为稍低密度,密度均匀,边界较清;增强后8例无明显强化,2例实质期出现轻微环状强化。结论多数肝淋巴瘤表现为肝弥漫性侵润,CT不能发现,少部分病例表现为肝结节或肿块,CT表现具有一定特征性,根据CT表现可以提示诊断,结合病史可以明确诊断。
Objective To improve the realization of CT characteristics in patients with liver lymphoma. Methods We retrospectively analysed the CT manifestations of 11 patients with liver lymphoma who were confirmed by pathology or clinical data, one of them was primary liver lymphoma, ten of them were secondary liver lymphoma.All the patients were examined with spiral CT, plain scaning and contrast-enhanced CT scans. Results In the one patient with primary liver lymphoma, CT plain scanning showed single low-attenuation lesions in the liver, After administrating contrast-medium there was no evident enhancement. In ten patients with secondary liver lymphoma,only one presented single liver lesion, the other 9 cases presented multiple lesions. CT plain scan showed low-attenuation lesions in all cases. After administrating contrast-medium, there was no evident enhancement of lesion intensity in eight cases and rim enhancement was seen in two cases. Conclusion Hepatic involvement is usually diffuse,most patterns of liver involvement are beyond the resolution for CT detection.Few liver involvement presented as nodus or mass. The CT manifestation of liver lymphoma has characteristics, which is useful for the diagnosis of the disease combining with clinical information of it.
