肾上腺少见原发肿瘤CT、MRI特征分析

Analysis of CT and MRI features of rare primary adrenal tumors

目的总结分析肾上腺少见原发肿瘤特征性影像学表现,以提高诊断水平。方法选取2018年3月至2022年5月我院收治的17例肾上腺少见原发肿瘤患者作为研究对象,总结其影像学表现。结果所有肿块均为单侧单发,其中节细胞神经瘤(GN)8例,节细胞神经母细胞瘤(GNB)1例,肾上腺神经鞘瘤(AS)2例,肾上腺皮质癌(ACC)3例,肾上腺畸胎瘤(AT)3例。CT及MRI检查能直观显示肿瘤位置、大小、形态、内部密度及信号、与周围组织结构的关系及有无发生转移。结论肾上腺少见原发肿瘤的影像表现形式多样,临床症状缺乏特异性,分析其影像学特征有助于提高术前诊断正确率。

Objective To summarize and analyze the characteristic imaging findings of rare primary adrenal tumors in order to improve the diagnostic level.Methods From March 2018 to May 2022,17 patients with rare primary adrenal tumors admitted in our hospital were selected as the research objects,and their imaging findings were summarized.Results All tumors were unilateral single,including 8 cases of ganglioneuroma(GN),1 case of ganglioneuroblastoma(GNB),2 cases of adrenal schwannoma(AS),3 cases of adrenocortical carcinoma(ACC)and 3 cases of adrenal teratoma(AT).CT and MRI examination can directly show the location,size,shape,internal density and signal of the tumor,the relationship with the surrounding tissue structure and the presence or absence of metastasis.Conclusion The imaging manifestations of rare primary adrenal tumors are diverse,and their clinical symptoms are lack of specificity.The analysis of their imaging features is helpful to improve the accuracy of preoperative diagnosis.
