摘要
目的探讨胰腺转移瘤的多层螺旋CT(MDCT)表现特点。资料与方法对56例胰腺转移瘤患者进行CT扫描,分析其临床资料及影像学特点。结果 56例共94处病灶,病灶直径为0.6~7.0 cm,平均2.3 cm,大部分(79处)边缘清晰。主要为单发结节(38例)或多发结节(12例),可发生于胰腺各部位。部分病灶表现为囊性(4例),少数伴胰管扩张(8例)或胆总管扩张(3例),极少数(2例)累及周围血管。48例(85.7%)同时伴有其他部位转移。增强扫描呈轻度强化、环形强化或显著强化。结论胰腺转移是恶性肿瘤的终末期表现之一,其MDCT表现具有一定的特征性,常伴胰腺以外其他脏器转移。
Objective To evaluate MDCT findings and characteristics of metastatic pancreatic tumors.Materials and Methods A total of 56 cases with metastatic pancreatic tumors performed computed tomography scan.The clinical data and CT characteristics were analyzed.Results The most frequently primary tumors were lung cancers(28 patients) and stomach carcinomas(13 patients).The main clinical symptoms were abdominal pain and epigastric discomfort.A total of 94 metastatic pancreatic tumors were detected.79 Well defined tumors were found in 56 patients.The range of diameters were from 0.6 to 7.0 cm,with the average of 2.3 cm.Tumors were single lesion in 38 patients and multiple lesions in 12 patients.Enhancement pattern of pancreatic metastatic tumors were cystic in 4 patients,homogeneous in 36 patients,rim enhancement in 12 patients.8 patients had dilated pancreatic ducts and 3 of them accompanied with dilated common bile ducts.Only 2 lesions infiltrated peripancreatic arteries.Meanwhile,47 patients with metastatic pancreatic tumors were found metastasis lesions in other organs.Conclusion Metastatic pancreatic tumors were the terminal stage of malignant tumors,which were frequently accompanied with metastasis lesions in other organs.
