目的探讨胰腺实性假乳头状瘤(SPTP)的CT表现,以提高该病的诊断水平。方法回顾性分析我院8例经术后病理确诊的SPTP的临床特征及CT影像资料,病例均行CT平扫及增强扫描检查。结果 8例患者中女性6例,男性2例,胰头部5例,胰体部1例,胰尾部2例,瘤体直径3.1-7.5cm。1例以囊性为主,2例以实性为主,5例囊实成分相仿,2例病灶有钙化。增强扫描动脉期肿瘤实性部分轻度强化,门静脉期肿瘤强化高于动脉期。结论胰腺实性假乳头状瘤的CT表现有一定的特征,可结合临床特点对其做出诊断和鉴别诊断。
Objective To explore the CT manifestations of solid pseudopapillary tumor of pancreas (SPTP) to improve the diagnosis of this disease. Methods The clinical features and CT images of 8 cases of SPTP confirmed by postoperative pathology were analyzed retrospectively. All patients underwent CT scan and enhanced scan. Results Among 8 patients, 6 were female, 2 were male, 5 were pancreatic head, 1 was pancreatic body and 2 were pancreatic tail. The diameter of the tumor was 3.1-7.5 cm. One case was cystic, the other two cases were mainly solid. Five cases had similar cystic components and two cases had calcification. Enhancement of the solid phase of the scan arterial phase of mild enhancement, portal vein tumor enhanced higher than the arterial phase. Conclusion The CT manifestations of solid pseudopapillary tumors of the pancreas have some characteristics that can be diagnosed and differentiated with clinical features.
