摘　　要：目的分析胰腺实性假乳头状瘤(solid pseudopapillary tumors of pancreas,SPTP)的CT表现。方法观察8例SPTP患者的CT表现,并与手术病理结果对照分析。结果 8例SPTP均为单发、外突性生长的囊实性肿块,其中4例呈类圆形,2例呈卵圆形,2例呈浅分叶状。增强后4例肿瘤实性部分轻中度强化,动脉期与门静脉期无明显差异。7例包膜完整,5例见壁结节,2例伴出血,5例伴钙化,1例伴胰管扩张,1例伴肝脏转移,1例伴胃后壁受侵。8例镜下见假乳头状结构以及出血、坏死及囊性变。结论 SPTP的CT表现具有一定的特征性,反映其病理特征,有助于诊断及鉴别诊断。Objective To analyze the CT features of solid pseudopapillary tumor of pancreas（SPTP）.Methods Eight patients with SPTP received triple phasic contrast-enhanced CT,and its consistency with pathological findings was analyzed.Results SPTP manifested as a solitary and exogenous mass,with a heterogeneous pattern composed of solid and polycystic parts.The shape of SPTP was spherical in four patients,oval in two patients,and shallow lobulation in another two patients.In contrast-enhanced phase images,the solid parts showed mild to moderate enhancement in both arterial and portal phases.Complete capsule was showed in seven patients,and nodules were found in the wall of mass in five patients.Hemorrhage was seen in two patients and calcification was showed in five patients.The dilation of pancreatic duct was found in one patient,liver metastases was showed in one patient,and the invasion of tumor to posterior gastric wall was found in one patient.Pseudopapillary structure,hemorrhage,necrosis,and cystic degeneration were showed in all patients by histological study.Conclusion SPTP has certain characteristic CT imaging manifestations consistent with histological features,which is helpful for the diagnosis and differential diagnosis of SPTP.
