【摘要】：目的探讨原发性胰腺淋巴瘤(PPL)的多层螺旋CT(MSCT)表现,以提高其认识和诊断水平。方法回顾性分析6例经手术及穿刺病理证实的PPL临床及MSCT资料,并复习文献。结果 6例病灶均为胰头部单发肿块,体积较大,平均直径约7.3 cm。形态不规则,与正常胰腺分界不清。MSCT上肿瘤平扫呈等或稍低密度,其中5例呈实性,密度均匀,增强呈轻度延迟性强化,强化程度稍低于周围正常胰腺。1例呈囊实性,增强后实性成分呈"快进慢出"强化方式,强化稍高于正常胰腺,囊变、坏死区无强化。6例肿瘤包绕血管,类似"血管漂浮征",病灶均无胰管扩张,无钙化,1例腹腔、腹膜后淋巴结肿大。结论 PPL具有相对特征性的影像学表现,结合相关临床资料,有助于提高其诊断准确率,确诊依赖病理。
[Abstract]:Objective to investigate the MSCT findings of primary pancreatic lymphoma (PPL) with multislice spiral CTT (MSCT), and to improve its recognition and diagnosis. Methods the clinical and MSCT data of 6 cases of PPL proved by operation and puncture pathology were retrospectively analyzed and the literature was reviewed. Results all the 6 lesions were solitary masses of the head of pancreas with a larger volume and an average diameter of 7.3 cm. The shape of the tumor was irregular, which was not clear to the normal pancreas. MSCT showed the same or slightly low density on plain scan. 5 cases showed solid, even density, slight delayed enhancement, and the enhancement degree was slightly lower than that of the surrounding normal pancreas. 1 cases showed cystic and solid enhancement, and the enhancement degree was slightly lower than that in the surrounding normal pancreas, and the enhancement degree was slightly lower than that in the surrounding normal pancreas. After enhancement, the solid components showed a "fast in and slow out" enhancement mode. The enhancement was slightly higher than that of the normal pancreas, cystic degeneration, and no enhancement in the necrotic area around the blood vessels, similar to the "vessel floating sign". There was no pancreatic duct dilatation and no calcification in the abdominal cavity of 1 case. Retroperitoneal lymphadenopathy. Conclusion PPL has relatively characteristic imaging findings, combined with relevant clinical data, it is helpful to improve the diagnostic accuracy and the diagnosis depends on pathology.
