多层螺旋CT对上腹部神经内分泌癌的诊断价值

目的：探讨多层螺旋CT诊断上腹部神经内分泌癌的价值。方法收集9例病理确诊的上腹部神经内分泌癌患者的多层螺旋CT影像资料，结合其临床表现及相关文献进行分析。结果9例患者中，单发6例，分别发生于胃、胰腺和腹腔；多发3例，发生于腹腔、胰腺、胃和十二指肠等器官。CT平扫均呈低或稍低密度灶，密度不均匀，增强不均匀强化，静脉期强化较动脉期明显，强化程度低于肝脏、胰腺等富血供器官。结论 CT检查对发生于上腹部的神经内分泌癌，尤其是对多发和有转移患者的诊断有重要价值。

Value of multi-slice spiral CT in the diagnosis of neuroendocrine carcinoma of the upper abdomen

Objective To investigate the value of multi-slice spiral CT in the diagnosis of neuroendocrine carci-noma of the upper abdomen. Methods The multi-slice spiral CT data of 9 patients with neuroendocrine carcinoma of the upper abdomen confirmed by pathology were collected, and their clinical manifestations and related literatures were analyzed. Results Among the 9 cases, 6 cases were found with single lesion, mostly located in the stomach, pancreas and peritoneal cavity, and 3 cases were found with multiple lesions, mostly in the peritoneal cavity, pancreas, stomach and duodenum. Plain CT images showed low or slightly low and uneven density lesions, with uneven enhancement. The enhancement in venous phase was more significant than that in arterial phase, and the enhancement degree was lower than that in liver and pancreatic hypervascular organ. Conclusion CT is valuable in the diagnosis of neuroendocrine carcinoma in the upper abdomen, especially in the patients with multiple and metastatic lesions.
