In order to analyze characteristic CT signs in the solid pseudopapillary tumor of the pancreas, a retrospective analysis was conducted on 49 patients with pseudopapillary tumor of the pancreas who where treated in Liaoning Cancer Hospital. All of the patients were confirmed by pathology, CT signs were analyzed and a pathology contrast was conducted. Furthermore, all cases had single lesions; 7 cases in the pancreatic head, 23 cases in the pancreatic body, 15 cases in the pancreatic body-tail and 4 cases in the pancreatic tail. The boundaries of the lesions were clear and the tumors, which may outline the pancreas, were composed of solid and polycystic parts. In addition, calcifications could be observed in the lesions and CT results revealed varying degrees of contrast enhancement of the solid components in the arterial phase, as well as a gradual contrast enhancement in the venous and delayed phase. Enhancement of capsule could be observed, and the enhancement region was observed in the solid part, no enhancement in cystic part.. In conclusion, CT manifestations of solid pseudopapillary tumors of the pancreas are specific, which is helpful to the diagnosis.
为分析胰腺实性假乳头状瘤的CT特征性表现，对辽宁省肿瘤医院收治的49例胰腺假乳头状瘤患者进行回顾性分析。所有患者均经病理证实，分析其CT表现并进行病理对照。此外，所有病例均为单发病变；胰头7例，胰体23例，胰体尾15例，胰尾4例。病变边界清晰，肿瘤可勾勒出胰腺轮廓，由实性和多囊性部分组成。此外，病变内可见钙化，CT结果显示动脉期实性成分有不同程度的强化，静脉期及延迟期强化逐渐明显。可见包膜强化，强化区域位于实性部分，囊性部分无强化。总之，胰腺实性假乳头状瘤的CT表现具有特异性，有助于诊断。
