目的探讨肾上腺节细胞神经瘤的CT表现特征,提高其CT诊断的准确性。方法回顾性分析经手术病理证实的10例肾上腺节细胞神经瘤患者的CT表现,并与病理进行对照分析。结果 10例肾上腺节细胞神经瘤均为单发病灶,术前均行CT平扫及动态增强扫描。肿瘤直径2.3～6.4 cm,平均3.8 cm。6例CT平扫为相对均匀的低密度,低于腹主动脉,近似水样密度,3例合并点状、条状钙化。增强扫描4例动脉期表现为无强化,6例表现轻微强化。所有病例静脉期均为轻度强化,较动脉期呈逐渐强化改变。1例出现细线状、分隔状强化,4例肉眼观类似囊性肿瘤。所有病例边界清楚,肿瘤质地较软,3例瘤体较大沿周围器官间隙呈嵌入性生长,推压或包绕邻近周围血管但血管无狭窄。结论肾上腺节细胞神经瘤瘤体较软,具有特定生长方式,瘤体较大时呈嵌入性生长。肿瘤平扫密度较低,部分肉眼观类似囊性肿瘤,动态增强扫描呈无强化或轻度强化,静脉强化呈渐进强化。
Objective To investigate the CT features of adrenal ganglioneuroma and to improve the accuracy of CT diagnosis. Methods The CT findings of 10 cases of adrenal ganglioneuroma confirmed by surgery and pathology were retrospectively analyzed and compared with the pathology. Results 10 cases of adrenal ganglioneuroma were single lesions, preoperative CT scan and dynamic enhanced scan. Tumor diameter 2.3 ~ 6.4 cm, an average of 3.8 cm. 6 cases of CT scan for the relatively uniform low density, lower than the abdominal aorta, similar to water density, 3 cases with dot-like, strip calcification. Enhanced arterial phase enhanced scan in 4 cases showed no enhancement, 6 cases showed slight enhancement. All cases were mild mild venous phase, compared with the arterial phase was gradually enhanced changes. 1 case appeared thin line shape, enhanced separation, 4 cases of macroscopic resembles cystic tumor. Clear border of all cases, the tumor texture is soft, 3 cases of tumor along the large organ interstices embedded growth, pushing or surrounding the surrounding blood vessels but no stenosis. Conclusion The adrenal ganglioneuroma tumor is relatively soft and has a specific growth pattern. When the tumor is large, the tumor is embedded. Low density of tumor plain scan, part of the macroscopic resembles cystic tumor, dynamic enhanced scan was no enhancement or mild enhancement, progressive enhancement of venous enhancement.
