肾上腺节细胞神经瘤的螺旋CT诊断价值

目的:分析肾上腺节细胞神经瘤的CT特征,提高CT对本病的诊断准确性。方法:回顾性分析6例经手术病理证实的肾上腺节细胞神经瘤的CT表现,并结合相关文献,探讨其影像学特征。结果:6例中4例病灶位于右侧,2例位于左侧。病灶呈圆形、椭圆形(5例)或不规则形(1例),边界清晰,无周围软组织和血管受侵犯征象。6例病灶密度均匀,其中2例病灶内有沙粒状钙化。增强扫描动脉期5例肿块无强化,1例无强化,静脉期及延迟期6例均呈轻度线条样或云絮样强化。结论:肾上腺节细胞神经瘤的CT表现有一定特征性,CT平扫和动态增强扫描对本病有重要诊断价值。

Value of CT in the diagnosis of adrenal ganglioneuroma

Objective.. To study the CT characteristics of adrenal ganglioneuroma in order to improve the accuracy of diagnosis. Methods：The CT findings of 6 cases with surgery and pathology proved adrenal ganglioneuroma were retrospec- tively analyzed,literatures were reviewed and their imaging characteristics were studied. Results：Of the 6 cases with adrenal ganglioneuroma,4 lesions were found in the right adrenal gland and 2 in the left. The lesions appeared as a round/oval/ ir- regular shaped, well demarcated mass, with no evidence of peripheral soft tissue or vascular invasion and homogeneous in density. 2 cases had intra tumoral punctate calcifications. After dynamic contrast enhanced scanning,no enhancement on ar- terial phase was showed in 5 patients, and moderate enhancement was showed in 1 patient,but mild linear or patchy en- hancement was assessed in parenchymal phase and delayed phase. Conclusion.. Certain CT characteristics could be revealed in adrenal ganglioneuroma and CT scanning without and with contrast enhancement plays an important role in the diagnosis of adrenal ganglioneuroma.
