目的：探讨肾上腺节细胞神经瘤的CT表现特征，以提高正确诊断率。方法回顾性分析经手术病理证实的6例肾上腺节细胞神经瘤的临床及CT表现，并与手术及病理结果行对照研究。结果6例肾上腺节细胞神经瘤均为单发病灶。CT平扫1例呈单囊性病灶，5例为实性，CT值20～42 HU，密度欠均匀，其中1例伴有点状钙化。肿瘤直径2.3～16.8 cm，平均5.4 cm。6例肿块呈椭圆形，边界均显示清楚，2例边缘稍不规则。增强扫描1例动脉期及静脉期见分隔样强化，3例延迟扫描见轻度强化。病理检查5例实性病灶表现为增生的神经纤维细胞、少量的成熟神经节细胞和间质血管增生，1例囊性病灶内可见大量黏液基质。结论肾上腺节细胞神经瘤CT表现具有一定特征，正确认识其影像学表现，有助于提高诊断率并减少误诊。

Objective To explore the CT features of adrenal ganglioneuroma so as to increase the rate of accurate diagnosis. Methods The clinical and CT manifestations were analyzed retrospectively in 6 patients with adrenal ganglioneuroma proved by pathology. The correlation study between CT and pathological findings was done. Results All of the 6 adrenal ganglioneuroma were solitary lesions. 1 case was unicystic lesion and 5 cases were solid lesions on plan scan. CT values of 6 cases were 20~42 HU and the density was not homogeneous, among which 1 case showed punctuate calcifications. The diameter of the tumor ranged from 2.3 cm to 16.8 cm with a mean of 5.4 cm. All of the 6 cases were oval in shape with defined border, among which there were 2 cases with irregular rim. 1 case demonstrated separated enhancement in artery and venous phase of enhanced scan and 3 cases showed slightly enhancement on delayed scan. There were proliferated neurofibra cells, sparing mature gangliocyte and mesenchyma vascular proliferation on pathologic examination in 5 cases with solid lesion and generous mucus matrix in 1 cystic case. Conclusion Adrenal ganglioneuroma has some specific CT features, which is helpful to increase the rate of accurate diagnosis and decrease misdiagnosis if these radiologic signs are well understood.
