胰腺神经内分泌肿瘤MSCT影像学表现及术前诊断价值分析

MSCT Imaging Feature of Neuroendocrine Tumor of Pancreas(NETP)and Its Preoperative Diagnostic Value

目的分析胰腺神经内分泌肿瘤(NETP)的MSCT影像学表现及术前诊断价值。方法回顾分析本院2017年3月至2019年10月收治19例NETP患者的临床资料。对MSCT检查结果进行讨论和分析,比较PNET与PNEC患者平扫、动脉期、静脉期MSCT值,分析两者影像学表现。结果PNET与PNEC患者MSCT值比较,差异无有统计意义(P>0.05)。PNET:实性病灶有9例,囊实性病灶2例;8例增强扫描可见中等强化,其中边缘环形强化3例,4例强化均匀,2例囊实性病灶的实性部分强化明显。PNEC:肿瘤呈不规则形7例,呈低密度;类圆形4例,呈稍低密度。其中1例患者可见钙化,1例呈囊实性改变;4例患者发生肝转移,3例发生淋巴结转移,有3例患者周围组织受到侵犯。结论MSCT检查可有效显示NETP的影像学特点,结合患者临床特点,可有效鉴别诊断良恶性NETP,为临床医师制定治疗方案提供可靠的依据。

Objective To analyze the MSCT imaging feature of neuroendocrine tumor of pancreas(NETP)and its preoperative diagnostic value.Methods The clinical data of 19 patients with NETP admitted to our hospital from March 2017 to October 2019 were retrospectively analyzed.The results of MSCT examination were discussed and analyzed.The MSCT values of PNET and PNEC patients in plain scan,arterial and venous phases were compared and the imaging findings were analyzed.Results There was no statistically significant difference in the MSCT values between PNET and PNEC patients(P>0.05).PNET:9 cases had solid lesions and 2 cases had solid and cystic lesions.In the enhanced scanning,8 cases showed moderate enhancement,including 3 cases with marginalenhancement like ring,4 cases of uniform enhancement,and solid part of solid and cystic lesions in 2 cases was significantly enhanced.PNEC:The tumor was irregular in 7 cases,showing a low density,and there were 4 cases with a round shape,showing a slightly lower density,in which 1 patient showed calcification and one patient had solid and cystic change,and 4 patients developed liver metastases,3 had lymph node metastasis,and there were 3 patients whose surrounding tissues were violated.Conclusion MSCT examination can effectively display the imaging features of NETP.The combining clinical features of patients can effectively differentiate benign and malignant NETP,and provide a reliable basis for clinicians to develop treatment plans.
