目的:对我院15例胰腺实性-假乳头状瘤患者的CT诊断特征及表现进行回顾。材料与方法:从我院2010年1月-2013年12月我院经由术中组织切除,通过病理以及免疫组织化学确诊的胰腺实性-假乳头状瘤患者中选取15例,分别对其进行CT平扫、增强扫描以及病理组织检测。结果:1肿瘤可分为囊性结构和实性结构两部分,CT平扫实性结构主要表现为等密度或者低密度,动态增强扫描,其动脉期呈现为轻度的强化,而门静脉期则表现为较为明显的强化,在增强扫描前后,其囊性部分均表现为低密度;210例患者的囊性与实性结构对比基本一致,1例患者则表现为以实性结构为主,另4例患者表现为囊性结构为主;34例患者表现出侵袭性,其肿瘤的包膜非常不完整,11例患者则表现出较为完整的包膜;4大部分的肿瘤均来自胰腺,且表现为椭圆形、圆形,多有较为完整的包膜,在经过增强处理后,可观察到有明显的强化,并且与胰腺有较为清晰的分界。结论:在CT诊断中,可观察到胰腺实性-假乳头状瘤患者表现出一定的特征,表明其具有重要的诊断价值,但注意与囊腺癌、胰腺假性囊肿等进行鉴别。 Objective: To review the CT features and performance of 15 patients with solid pancreatic pseudopapillary tumor in our hospital. MATERIALS AND METHODS: From January 2010 to December 2013 in our hospital, 15 cases of pancreatic parenchyma-pseudopapillary tumor confirmed by pathology and immunohistochemistry were selected for resection in our hospital. CT scan, enhanced scan and pathological examination. Results: 1 The tumor can be divided into two parts: the cystic structure and the solid structure. The CT plain structure is mainly characterized by isodense or low-density, dynamic contrast-enhanced scanning. The arterial phase presents mild enhancement, while the portal vein Showed more obvious enhancement before and after enhanced scan, the cystic part of the performance of low density; 210 cases of cystic and solid structure is basically the same, one case was characterized by solid structure-based, and the other Four of the patients showed cystic structures predominantly; 34 patients showed invasiveness with a very incomplete envelope of the tumor and 11 patients with a more complete envelope; 4 the majority of tumors were from the pancreas and The performance of oval, round, and more complete capsule, after enhanced treatment, can be significantly enhanced, and the pancreas have a more clear boundaries. CONCLUSIONS: In the diagnosis of pancreatic solid-pseudopapillary tumor, some features may be observed in the CT diagnosis, indicating that it has important diagnostic value, but attention should be paid to differentiate between cystadenocarcinoma and pancreatic pseudocyst.
