肾上腺节细胞神经瘤的CT表现

目的 探讨肾上腺节细胞神经瘤的CT表现特征，提高诊断水平。资料与方法 回顾性分析7例经手术病理证实的肾上腺节细胞神经瘤的CT表现，并作文献复习。结果 肾上腺节细胞神经瘤的CT表现有以下特点：肿块边界清晰，多呈卵圆形，密度较均匀，平扫密度低于竖脊肌，常见小点状钙化，偶有囊变；增强扫描呈轻、中度不均匀强化，强化程度弱于竖脊肌。结论 肾上腺节细胞神经瘤的CT表现具有一定特征性，认识该CT表现特征有助于与其他肿瘤鉴别。

CT Findings of Adrenal Ganglioneuromas

Objective To investigate the CT features of adrenal ganglioneuromas, and improve the diagnostic level of adrenal ganglioneuromas.Materials and Methods The CT findings of 7 cases with adrenal ganglioneuromas proved by operation and pathology were retrospectively analyzed, and a literature review was also reviewed.Results The CT characteristics of adrenal ganglioneuromas were as follows: The tumors were appeared well defined, the most of masses were orbicular ovate with homogeneous density lower than that of sacrospinal muscle in nonenhanced CT, scattered punctate calcification were seen frequently inside tumor with cystic area incidentally, slight or moderate inhomogeneous enhancement were observed inside tumors, the degree of enhancement of lesions was lower than that of sacrospinal muscle.Conclusion The CT findings of adrenal ganglioneuromas are characteristic to some extent. To master the CT characteristics of adrenal ganglioneuromas can help us to discriminate it from other tumors.
