目的：分析肾上腺节神经细胞瘤（Adrenal Ganglioneuroma，AGN）的CT及MRI表现。方法收集该院2010年9月-2014年10月期间收治的32例经手术、病理证实的AGN患者，回顾性分析AGN患者的CT及MRI表现，分析肿瘤的位置、形态、密度或信号及其强化方式。结果32例AGN中18例位于右侧（占56.3%），14例位于左侧（占43.7%）；CT显示平扫后，24例呈均匀低密度（占75%），8例呈不均匀低密度（占25%），其中17例瘤内可见散在的斑点状、小条状钙化（占53.1%），增强扫描后6例未见明显强化（占18.7%），26例瘤内可见不均匀轻、中度强化（占81.3%）；其中12例行MRI平扫及增强扫描, MRI显示瘤体呈T1WI等低信号，T2WI不均匀高信号，其中4例（占33.3%）可见条状、片状或漩涡状低信号，DWI呈稍高信号，增强后动脉期呈轻度强化，门脉期及延迟期呈渐进性不均匀轻中度强化。结论AGN的CT及MRI表现具有一定的特征性，将二者结合可提高其诊断率。
目的：分析腎上腺節神經細胞瘤（Adrenal Ganglioneuroma，AGN）的CT及MRI錶現。方法收集該院2010年9月-2014年10月期間收治的32例經手術、病理證實的AGN患者，迴顧性分析AGN患者的CT及MRI錶現，分析腫瘤的位置、形態、密度或信號及其彊化方式。結果32例AGN中18例位于右側（佔56.3%），14例位于左側（佔43.7%）；CT顯示平掃後，24例呈均勻低密度（佔75%），8例呈不均勻低密度（佔25%），其中17例瘤內可見散在的斑點狀、小條狀鈣化（佔53.1%），增彊掃描後6例未見明顯彊化（佔18.7%），26例瘤內可見不均勻輕、中度彊化（佔81.3%）；其中12例行MRI平掃及增彊掃描, MRI顯示瘤體呈T1WI等低信號，T2WI不均勻高信號，其中4例（佔33.3%）可見條狀、片狀或漩渦狀低信號，DWI呈稍高信號，增彊後動脈期呈輕度彊化，門脈期及延遲期呈漸進性不均勻輕中度彊化。結論AGN的CT及MRI錶現具有一定的特徵性，將二者結閤可提高其診斷率。

Objective To analyze the appearances of CT and MRI in adrenal ganglioneuroma. Methods 32 cases of adrenal ganglioneuroma confirmed by surgery and pathology which were collected September 2010 to October 2014 retrospectively analyzed. Tumor location, shape, density, or signal intensity and enhancement pattern were studied at CT and MRI. Results 18 cases of all samples were located on the right adrenal gland (56.3%), and 14 cases were located on the left (43.7%). Plain and enhanced CT were performed, which studies showed 24 lesions homogeneous low density (75%), 8 cases were heterogeneous low density (25%), scattered punctate, small strips calcification was seen in 17 cases (53.1%). After enhancement scan, 6 cases had no obvious enhancement (18.7%), and 26 cases of tumor were less uniform light and moderate enhancement (81.3%). 12 cases were scanned by MRI plain scan and enhanced scan, the results showed that tumors had homogeneous low signal intensity on T1WI and heterogeneous hyper-intensity on T2WI. The strip, flake or swirl low signal were seen in 4 cases (33.3%) on T2WI. The lesions showed hyperintensity on DWI. The slight enhancement was seen in the arterial phase and gradually stronger enhancement during the delayed phase after contrast administration. Conclusion CT and MRI of adrenal ganglioneuroma had certain characteristic, which were valuable in differential diagnosis of adrenal ganglioneuroma.
