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 CT findings of solid pseudopapillary tumors of pancreas (SPTP). Methods The CT findings of 8 patients with SPTP were observed and compared with the results of surgical pathology. Results All the 8 cases of SPTP were cystic solid tumors with solitary and extroverted growth. Among them, 4 cases were round, 2 cases were oval and 2 cases were light lobulated. After the enhancement, the solidity of the 4 cases was mild to moderate enhancement, and there was no significant difference between the arterial phase and the portal vein. Seven cases had complete capsule, five cases with wall nodules, two cases with hemorrhage, five cases with calcification, one case with pancreatic duct dilatation, one case with liver metastasis and one case with gastric wall invasion. 8 cases of pseudopapillary mirror see the structure and bleeding, necrosis and cystic degeneration. Conclusion The CT findings of SPTP have certain characteristics, which reflect the pathological features of SPTP, which is helpful to the diagnosis and differential diagnosis.
