| 中文摘要: |
| 目的 探讨肾上腺节细胞神经瘤的MSCT表现。方法 回顾性分析10例经手术病理证实的肾上腺节细胞神经瘤的影像学资料，观察病灶的部位、形态、大小、MSCT表现及周围组织结构的关系，并测量平扫、动脉期、静脉期、延迟期的CT值。结果 所有病例均为单发病灶，其中4例病灶位于左侧肾上腺，6例位于右侧肾上腺，与周围组织结构分界清晰，2例呈椭圆形，6例呈水滴形，2例呈不规则分叶状。MSCT平扫病灶均表现为低密度，3例病灶内部见点状高密度钙化灶；增强扫描动脉期均未见明显强化，静脉期及延迟期病灶边缘或内部可见渐进性强化。平扫、动脉期、静脉期及延迟期病灶的CT值分别为（29.71±9.93） HU、（31.76±9.91） HU、（37.86±10.18） HU及（41.04±10.89） HU。结论 肾上腺节细胞神经瘤的MSCT表现具有一定的特征性，有助于该病的诊断及鉴别诊断。 |

| Objective To investigate MSCT findings of adrenal ganglioneuroma. Methods Image data of 10 patients with adrenal ganglioneuroma confirmed by histopathology were analyzed retrospectively, the location, morphology, size, MSCT findings, and the relationship between the lesion and surrounding structures were analyzed. CT value was measured in plain scan, arterial phase, venous phase and delayed phase. Results Ten cases were located on single adrenal glands with clear boundary (4 cases on the left, 6 cases on the right), the morphology was showed ellipse in 2 cases, 6 cases were showed water-drop appearances, 2 cases were irregularly lobulated. The lesions were all showed low density on CT plan scan, small punctate calcifications were found in 3 cases; the lesions were not significant enhancement in arterial phase, which were continous enhancement in the venous phase and delayed phase. CT value was (29.71±9.93)HU, (31.76±9.91)HU, (37.86±10.18)HU and (41.04±10.89)HU in plain scan, arterial phase, venous phase and delayed phase, respectively. Conclusion There are specific MSCT findings for the ganglioneuroma occurred in adrenal gland, which may be helpful to diagnosis and differential diagnosis. |
