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 investigate the CT findings of pancreatic secondary lymphoma in order to improve the understanding and diagnosis of this disease. Materials and Methods The CT and clinical data of 5 patients with pancreatic secondary lymphoma were retrospectively analyzed and compared. Results 5 cases of pancreatic secondary lymphoma are non-Hodgkin’s lymphoma. All cases underwent abdominal CT scan and enhanced scan, of which 4 cases of nodules (mass), diffuse in 1 case. A total of 5 lesions were found, the maximum diameter of 1.0 ~ 10.1 cm, an average of 5.1 cm. CT lesions showed low density all three cases of liquefaction necrosis. The CT value of the lesion was 23.2-34.1 HU (average 28.5 HU), 44.8-70.9 HU (mean 57 HU), 46.4-94.8 HU (69.2 HU) in the arterial phase, 2 significantly enhanced, 3 cases of moderate enhancement, liquefied necrosis area is not enhanced. Conclusions Pancreatic secondary lymphoma is rare, CT dynamic enhancement was progressive enhancement, and definite diagnosis should be combined with clinical data.
