摘要
目的:分析胰腺实性-假乳头状瘤的CT表现,探讨CT对该肿瘤的诊断价值。材料和方法:回顾性研究经手术、病理证实的5例胰腺实性-假乳头状瘤的CT表现。结果:肿瘤内有实性和囊性结构,CT平扫实性结构呈低或等密度,增强后动脉期呈轻度强化、门静脉期呈明显强化,囊性部分在增强前后均呈低密度;特征性表现为“溶冰征”。肿瘤大部分位于胰腺,多有完整包膜,不伴有胆总管和胰管扩张。结论:胰腺实性-假乳头状瘤的CT表现有一定特征,有助于诊断。
To study the CT manifestations of the solid - pseudopapillary tumors of the pancreas （SPTP） and to explore the CT diagnostic value. Materials and Methods： CT features of five patients with pathologically proved SPTP were retrospectively analyzed. Results： There were solid and cystic structures within the neoplasm, the solid portions demonstrated hypo - or iso - attenuation on pre - contrast CT, and slight enhancement in the arterial phase and marked enhancement in the portal venous phase on post - contrast CT scan. The cystic portions appeared hypo - attenuation on both pre - and post - contrast views. The ＂ice - liquefying＂ sign was characteristic. The tumor was mainly located in the pancreas with complete capsule, no common bile duct or pancreatic duct dilatation was accompanied. Conclusion.＂ The CT characteristic findings of SPTP might be of great value for the diagnosis. SPTP should be differentiated from mucous cystadenoma, mucous cystcarcinoma, and pseudo - cyst of the oancreas.
