目的：总结肾上腺节细胞神经瘤的M SC T和超声表现，进一步提高对本病的诊断水平。方法回顾性分析8例经手术和病理证实的肾上腺节细胞神经瘤的 MSCT 和超声征象。结果8例病变均单侧发病，MSCT 表现：8例M SC T平扫均表现为肾上腺区密度均匀的软组织肿块影，5例肿块边缘受压变形，3例外观呈较规整的椭圆形，其中4例不规则形和1例椭圆形肿块边缘可见伪足样尖角。8例CT 值14．9～34．3HU ，平均CT 值25．3HU ，8例肿块边缘均较清楚，5例下腔静脉可见较明显的受压推移。8例病变动脉期强化轻微，CT值19．5～37．8HU ，平均30．1HU ，静脉期CT值23．3～39．8HU ，平均32．5HU ，延迟期CT值27．5～40．9HU ，平均36．1HU。8例三期动态增强扫描整体呈渐进性轻度强化，5例于静脉期及平衡期可见肿块内线条状强化影。超声表现：8例于患侧肾上腺区探及低回声结节，回声均匀；CDFI示5例病变内见少许斑点状血流信号，3例未见明显血流信号。8例形态均较规则，边界均较清楚，包膜回声较强且连续完整。结论肾上腺节细胞神经瘤具有较强的M SC T和超声征象，对指导临床治疗具有重要意义。

Objective To summarize the ultrasound and MSCT features of adrenal ganglioneuroma and to improve the di‐agnostic level of this disease .Methods We analyzed MSCT and sonographic features of 8 cases of adrenal ganglioneuroma confirmed by operation and pathology review .Results The lesions of 8 cases were unilateral .MSCT :8 cases of MSCT scan showed adrenal gland density soft tissue mass ,5 cases of the tumor edge compression deformation ,3 cases of the ap‐pearance of a more standard elliptic ,among which 4 cases were irregular in shape and 1 case was oval mass as pseudopodi‐um sharp edge CT value of was 14 .9~34 .3 HU ,with the average CT value of 25 .3 HU ,8 cases had clear edge ,5 cases of inferior vena cava were obviously compressed .8 cases of mild lesions were enhanced in the arterial phase ,CT value was 19 .5~37 .8 HU ,average 30 .1 HU ,venous phase CT value was 23 .3~39 .8 HU ,the average delay time was 32 .5 HU , CT value was 27.5~40 .9 HU ,with average of 36 .1 HU .8 cases of three dynamic enhanced scan showed progressive en‐hancement in 5 cases ,venous phase and equilibrium phase visible mass inside the strip enhancement .Ultrasound showed the ipsilateral adrenal area exploration and hypoechoic nodule in 8 cases ,with homogeneous echo ;CDFI showed a few spots of blood flow signal in 5 cases ,3 cases showed no obvious blood flow signal .8 cases were compared with the rules , boundaries were clear ,the echo envelope was bright and continuous .Conclusion Adrenal ganglioneuroma presents with typical MSCT and ultrasonographic features ,which has important significance to guide the clinical treatment .
