摘要
目的探讨胰腺继发性淋巴瘤的CT表现,以提高对该病的认识和诊断水平。资料与方法回顾性分析5例胰腺继发性淋巴瘤患者的CT和临床资料,并作对照分析。结果 5例胰腺继发性淋巴瘤均为非霍奇金淋巴瘤。所有病例均行腹部CT平扫和增强扫描,其中结节（肿块）型4例,弥漫型1例。共发现5个病灶,最大直径1.0-10.1 cm,平均5.1 cm。CT平扫所有病变均呈低密度,3例有液化坏死。病变实性部分CT值23.2-34.1 HU（平均28.5 HU）;增强动脉期CT值44.8-70.9 HU（平均57 HU）,静脉期CT值46.4-94.8 HU（平均69.2 HU）,2例明显强化,3例中度强化,液化坏死区域不强化。结论胰腺继发性淋巴瘤较少见,CT动态增强呈进行性强化,明确诊断需结合临床资料。
Objective To analyze the CT characteristics of pancreatic secondary lymphoma,in order to improve the diagnosis.Materials and Methods Five cases of patients with pancreatic secondary lymphoma were reviewed.The CT data and clinical results were analyzed retrospectively.Abdomen CT plain scan and enhanced scan was performed in all cases.Results The pancreatic secondary lymphomas were non Hodgkin lymphomas.Four tumors were nodular type,1 was diffuse type.The diameter of 5 pancreatic lesions was 1.0-10.1 cm,with a mean diameter of 5.1 cm.Tumors showed low density on plain CT scan.Three cases showed necrosis.The lesions showed obviously enhancement in 2 cases,moderate enhancement in 3 cases on enhanced CT.Conclusion Pancreatic secondary lymphoma is rare.Dynamic CT scans,combined with clinical informations,can make a definite diagnosis.
