摘要
目的分析胰腺类癌的临床特征和CT表现,提高对该病的诊断水平。资料与方法3例经手术和病理证实的胰腺类癌患者,术前均接受了CT检查,其中1例接受了上消化道钡餐检查。结果3例患者均为胰腺单发的囊实性肿块,1例位于胰头、2例位于胰尾,肿块包膜完整,边界清晰。CT平扫实性成分的CT值为22～34 HU,平均27 HU。增强后实性部分在动脉期呈显著环形强化,CT值40～88 HU,平均55 HU,高于胰腺实质。门静脉期肿块实性成分强化程度明显降低,CT值50～72 HU,平均62 HU,略高于胰腺实质。其中1例患者接受上消化道钡餐检查,可见十二指肠圈明显受压移位,但肠黏膜未见破坏。结论胰腺类癌的影像表现具有一定特征性,结合病理检查,能为临床诊断提供帮助。
Objective To investigate the clinic features and CT findings of pancreatic carcinoid,and improve its diagnostic accuracy. Materials and Methods CT was performed in all 3 patients with pancreatic carcinoid proved surgically and pathologically,and upper gastrointestinal barium meal examination was performed in 1 patient. Results All 3 patients were depicted as single solid-cystic mass with clear border in the area of pancreas.1 case located at pancreatic head and 2 cases in pancreatic the tail.CT value of solid component was 22-34Hu,average 27Hu.Solid part of mass was obvious ring-like enhancement after contrast,CT value of solid component was 40-88Hu,average 55Hu.Enhancement of solid part of mass was decreased in portal phase,50-72Hu,average 62Hu.1 case accepted the examination of upper gastrointestinal barium meal,duodenal compression ring and shift can be seen clearly without damage of intestinal mucosa. Conclusion The CT characteristics of pancreatic carcinoid is helpful to clinical diagnosis.
