The findings of computed tomography (CT) in seven patients with pancreatic pseudocysts involving the duodenum are reported. Specific CT characteristics of duodenal wall involvement by the pseudocysts are tubular configuration of the pseudocyst, extending along the wall and conforming to the course of the duodenum (seven of seven), and abrupt flattening of the otherwise tubular or spherical pseudocyst at the border of the duodenal lumen (five of seven). The second part of the duodenum was involved in all cases; in some cases the first part of the duodenum was also involved (two of seven), and in others the pseudocyst extended to the third part of the duodenum (two of seven). All patients had other CT evidence of pancreatitis in addition to duodenal pseudocysts. CT findings are compared to other imaging methods and clinical and surgical findings. Patients with duodenal pseudocysts should be watched carefully for signs and symptoms of gastric outlet obstruction, since this was a prominent clinical problem in six of seven patients, and gastric outlet obstruction complicating suspected pancreatitis should alert to the possibility of duodenal pseudocyst.
本文报告了7例胰腺假性囊肿累及十二指肠患者的计算机断层扫描（CT）结果。假性囊肿累及十二指肠壁的特异性CT表现为：假性囊肿呈管状形态，沿十二指肠壁延伸并与十二指肠走行一致（7例均如此）；在十二指肠管腔边界处，原本呈管状或球形的假性囊肿突然变平（7例中有5例）。所有病例均累及十二指肠第二部；部分病例还累及十二指肠第一部（7例中有2例），另一些病例中假性囊肿延伸至十二指肠第三部（7例中有2例）。除十二指肠假性囊肿外，所有患者均有其他胰腺炎的CT证据。将CT结果与其他影像学检查方法、临床及手术结果进行了比较。十二指肠假性囊肿患者应密切观察有无胃出口梗阻的体征和症状，因为这是7例患者中6例的突出临床问题，疑似胰腺炎合并胃出口梗阻应警惕十二指肠假性囊肿的可能。
