目的:分析胰腺导管腺癌( PDAC)与非功能胰岛细胞瘤( NICT)的临床特点。方法回顾性总结我院收治的15例PDAC与21例NICT的临床症状、CT表现,并对比分析肿瘤学特征与CT影像学关系。结果 PDAC CT平扫可显示肝内、外胆管扩张,胆囊胀大,胰管扩张(正常直径﹤3 mm),胰头部占位性病变,同时又可以观察有无肝转移和淋巴结转移。胰腺区动态薄层增强扫描可获得更佳效果,且不受肠胀气影响。对于瘤体较小的NICT者,CT平扫难以发现,增强扫描动脉期明显强化,静脉期稍微减弱。结论结合临床表现、组织学特征结合CT影像检查有助于PDAC与NICT的鉴别诊断。
目的:分析胰腺導管腺癌( PDAC)與非功能胰島細胞瘤( NICT)的臨床特點。方法迴顧性總結我院收治的15例PDAC與21例NICT的臨床癥狀、CT錶現,併對比分析腫瘤學特徵與CT影像學關繫。結果 PDAC CT平掃可顯示肝內、外膽管擴張,膽囊脹大,胰管擴張(正常直徑﹤3 mm),胰頭部佔位性病變,同時又可以觀察有無肝轉移和淋巴結轉移。胰腺區動態薄層增彊掃描可穫得更佳效果,且不受腸脹氣影響。對于瘤體較小的NICT者,CT平掃難以髮現,增彊掃描動脈期明顯彊化,靜脈期稍微減弱。結論結閤臨床錶現、組織學特徵結閤CT影像檢查有助于PDAC與NICT的鑒彆診斷。

Objective To analyze the clinical features of pancreatic ductal adenocarcinoma ( PDAC)and nonfunctional islet cell tumor( NICT). Methods The clinical symptoms and CT presentation of 15 PDAC cases and 21 NICT cases were studied retrospectively. Relationship between oncological fea-tures and CT imaging were compared and analyzed. Results For PDAC,plain CT scanning could reveal intrahepatic and extrahepatic expansion of the bile duct,swollen gallbladder,pancreatic duct dilation( di-ameter﹤3mm)and occupancy lesions of the pancreatic head. At the same time,liver and lymph node me-tastasis could also be observed. Thin-layer scanning with dynamic enhancement could achieve a better effect and it′s not affected by the intestinal tympanites. Most small NICT tumors were difficult to be detec-ted by the plain scanning,but they could be markedly enhanced in the arterial phase and slightly enhanced in the portal venous phase. Conclusion Clinical symptom,pathologic features and CT scanning are help-ful to differentiate PDAC and NICT.
