生殖系统神经内分泌肿瘤CT表现

CT characteristics of reproductive neuroendocrine tumor

目的观察神经内分泌肿瘤的病理及CT影像学特点。方法回顾性分析3例经手术病理证实的女性生殖系统神经内分泌肿瘤的CT影像资料,并结合临床、病理资料进行分析。结果①肿瘤多为单发,一般体积较大,密度不均,内可见囊变坏死。②增强扫描动脉期肿块内多可见粗大血管影,静脉期呈持续强化,CT值多在62HU左右。③多数肿瘤周边可见纠集血管影。结论生殖系统神经内分泌肿瘤CT表现具有一定特征性,对该病的诊断及鉴别诊断有重要意义。

Objective To investigate spiral CT findings and the pathology of reproductive neuroendocrine tumor. Meth- ods The clinical and serial materials of 3 cases＇APUD which were confirmed by clinical operation were retrospectively analyzed, and its imaging features were summarized. Results （1）Most of the tumors exist alone, and the dimension is larger,the density is nonuniform, the cyst becomes thanatosis inside, which is in keeping with Raymond E＇ report. （2）If enhancing the arterial scan of CT,large vessels shadow can be seen inside the cyst, the venous phase presents continuous strengthening, most of the value is about 62HU. （3）Large vessels shadow get together around most of the tumor. Conclu- sion The imaging findings of CT possess relative feature, and it has great value for the diagnosis and differential diagno- sis of the neuroendocrine tumor in the reproductive system.
