摘要 目的:探讨胰腺实性假乳头状瘤(SPTP)的CT表现特点,提高诊断水平。方法:回顾性分析经病理证实的9例SPTP的CT表现。结果:4例SPTP位于胰头,2例位于胰尾,1例位于胰头颈,2例胰体尾部均受累及,直径4.3~15.7cm。多数呈圆形或椭圆形。多数肿瘤为囊实性,3例伴有出血,5例可见钙化,其中1例为实性部分团块状钙化,1例为边缘蛋壳状钙化。增强扫描动脉期肿瘤实性部分轻度强化,门静脉期呈明显强化,2例位于胰头部SPTP引起胰胆管扩张。结论:SPTP的CT表现具有一定特征,结合临床特点可以做出诊断和鉴别诊断。 Objective:To explore the CT findings of solid-pseudopapillary tumors of the pancreas (SPTP), and to improve the diagnostic level of the disease, Methods.. The findings of CT imaging in 9 cases with pathologically proved SPTP of pancreas were analyzed retrospectively. Results.. 4 tumors were located in the head of pancreas, 2 in tail, 1 in head and neck, 2 in body and tail, with the diameter ranging from 4.3 to 15, 7 cm. Most lesions were round or elliptical, including cystic and solid portion. Haemorrhage were seen in 3 cases, Calcification were seen in 5 cases, with masslike calcification in solid part of 1 case, and eggshell calcification in 1 case, The solid part of the tumors were enhanced slightly in the arterial phase and markedly in the portal venous phase. The dilation of pancreatic and bile duct were found in I case locating in pancreatic head. Conclusion:There are some characteristics on CT manifestation of SPTP. The correct imaging diagnosis and differential diagnosis is possible based on clinical characteristic and CT findings.
