摘    要:目的 探讨胰腺实性-假乳头状瘤(SPTP)的CT特征,并与临床、病理对照,以提高该病的诊断正确率.方法 回顾性分析2005年3月至2006年2月经术后病理证实的5例SPTP患者的CT表现,其中女4例,男1例,年龄10~29岁,平均年龄(16.20±7.49)岁.术前5例患者均行CT检查及增强扫描检查.4例行胰十二指肠切除术,1例行胰体尾部肿瘤切除术.结果 肿瘤位于胰头和颈部者4例,胰体和尾部者1例,肿块边界均清晰,肿块直径3.0~9.0 em,平均5.2 cm.2例以囊性成分为主,2例以实性成分为主,1例囊、实性成分比例相仿.CT增强扫描示肿瘤实性部分呈逐渐强化,但始终低于正常胰腺组织.1例肿块边缘可见不连续环形钙化,1例合并轻度胰管扩张,无一例出现远处转移.结论 SPTP的CT表现有一定的特点,CT结合临床特征有助于该病的诊断.

Abstract:Objective To evaluate the features of solid-pseudopapiHary tumors of pancreas (SPTP),and to compare with the clinical and pathological findings in order to improve the diagnostic accura-cy.Methods The CT appearances were analyzed retrospectively in 5 patients with pathologically proven SPTP.There were 4 women and 1 man,with the mean age of(16.20±7.49)years.Plain CT and contrasted CT were performed in all 5 cases.Results The tumors of 4 caseswerelocatedinthe head and neck of pan-creats and 1 case was in the body and tail of pancreas.Clear tumor margins were seen in all cases.The mean diameter of these tumors was 5.2 cm(3.0-9.0 cm).Two cases were predominantly composed of cystic por-tions,2 cases were mainly composed of solid portions,and 1 case was composed of similar proportions of solid and cystic portions.Inhomogeneous enhancement Was rewealed in contrasted CT scan,but Was lower in both phase than normal pancreas.Tumor border discontinuous ring-shape calcification was seen in 1 case,dilata-tion of the main pancreatic duct Was demonstrated in 1 case and no metastasis were seen.Conclusions Certain CT features may suggest the diagnosis of SPTP.CT combined with the clinical feature is helpful to the diagnosis.
