目的：回顾性研究24例胰腺内转移瘤的横断面影像学诊断标准。材料与方法：由两名放射科医师对胰腺进行超声和CT复查，并确定其形态学类型。胰腺转移瘤多为单发多发结节10例，超声表现为均匀低回声结节15例，CT表现为低密度结节11例，有时为多血供结节6例，有时为假囊性结节4例。动态增强CT显示直径10 mm的小病灶（3例），在US上看不到，当它显示腺体中的几个结节时高度提示。我们确定了胰腺内转移性疾病的其他一些标准：胰腺内有两个或多个位置，无论病变大小，胰后脂肪未闭塞，胰头大肿瘤的胆管树未扩张，以及无内分泌综合征的富血供肿块。经皮穿刺评估的诊断（10例），并从原发性导管腺癌pancreat.Conclusion：检测和识别胰腺转移瘤的提示功能，可以通过检查胰腺动态CT。
Objective: Twenty-four patients with intrapancreatic metastases were retrospectively studied to identify diagnostic criteria on cross-sectional imaging.Materials and Methods: Ultrasound and CT of the pancreas were reexamined by two radiologists who specified morphologic patterns.Results: Metastases of the pancreas were found more often solitary (14 cases) than multiple (10 cases) and as homogeneous nodules hypoechoic on US (15 cases), hypodense on CT (11 cases), sometimes hypervascular (6 cases) or pseudocystic (4 cases). Dynamic contrast-enhanced CT demonstrated small lesions 10 mm in diameter (three cases), not seen on US, and was highly suggestive when it showed several nodules in the gland. We identified some other criteria of intrapancreatic metastatic disease: two or more locations in the pancreas, nonobliteration of the retropancreatic fat regardless of the size of the lesion, nondilated biliary tree in the case of a large tumor of the pancreatic head, and a hypervascular mass without endocrine syndrome. Percutaneous puncture assessed the diagnosis (10 cases) and differentiated metastases from a primary ductal adenocarcinoma of the pancreas.Conclusion: Detection and identification of suggestive features of pancreatic metastases may be obtained by examination of the pancreas with dynamic CT.
