目的探讨胰腺导管腺癌和肿块型胰腺炎的CT特征。方法选取2009年5月～2011年5月经手术病理证实为胰腺导管腺癌的患者22例和肿块型胰腺炎的患者24例,对其CT诊断资料进行回顾性分析。结果肿块型胰腺炎与胰腺导管癌比较,CT征象中沿主胰管走向分布钙化灶(40.0%、0%)、肝转移(0%、25.0%)、腹部淋巴结肿大(0%、33.3%)、胰周大血管包埋包绕侵袭(0%、50.0%)、腹膜后直接侵犯(0%、50.0%)、胆管与胰管均扩张(13.6%、41.7%)、胆总管下段扩张呈现出突然狭窄截断(18.2%、75.0%)比较差异有统计学意义(P<0.05)。结论将胰腺导管腺癌和肿块型胰腺炎的CT征象合其临床表现、病史及实验室检查等,能进行准确、有效地诊断与鉴别诊断,但CT表现无异常的患者不能完全排除存在胰腺癌的可能,需要进一步结合临床确诊。
Objective To investigate the CT features of pancreatic adenocarcinoma and mass pancreatitis. Methods From May 2009 to May 2011, 22 patients with pancreatic ductal adenocarcinoma confirmed by surgery and pathology and 24 patients with mass pancreatitis were selected. The diagnostic data of CT were retrospectively analyzed. Results Compared with pancreatic ductal adenocarcinoma, the CT signs of calcification (40.0%, 0%), liver metastasis (0%, 25.0%), abdominal lymph node enlargement (0%, 33.3% (0%, 50.0%), direct retroperitoneal invasion (0%, 50.0%), dilatation of bile ducts and pancreatic duct (13.6%, 41.7%), dilatation of lower common bile duct A sudden narrow cut-off (18.2%, 75.0%) was statistically significant difference (P <0.05). Conclusions CT findings of pancreatic ductal adenocarcinoma and pancreatitis of the pancreas can be accurately and effectively diagnosed and differentiated with clinical manifestations, medical history and laboratory tests. However, patients with abnormal CT findings can not completely exclude the presence of pancreatic cancer The possibility, need to be further combined with clinical diagnosis.
