【摘要】：目的:探讨节细胞神经瘤与节细胞神经母细胞瘤的CT表现特点及其鉴别诊断。方法:回顾性分析本院经手术病理证实的28例节细胞神经瘤及2例节细胞神经母细胞瘤患者的病例资料,所有患者均行CT平扫及增强检查。结果:28例节细胞神经瘤中,位于肾上腺区15例、胸段脊柱旁6例、腰段脊柱旁2例、颈鞘区4例、骶前区1例;肿瘤表现为圆形、类圆形、水滴状软组织肿块,边界清晰、边缘光滑;14例可见点状钙化;16例有伪足征;24例密度均匀,4例密度不均匀,1例含有脂肪成分。增强扫描轻度强化,11例呈片絮状延迟强化。2例节细胞神经母细胞瘤均位于肾上腺区,CT表现为不规则软组织肿块,密度不均匀,其内见明显坏死、囊变、粗大钙化,增强扫描明显不均匀强化,1例伴淋巴结转移。结论:节细胞神经瘤与节细胞神经母细胞瘤CT表现具有一定特征,CT对其定性诊断具有重要价值,出现肿块内粗大钙化、边界模糊、周围组织侵犯及淋巴结转移时,应考虑节细胞神经母细胞瘤的可能。
[Abstract]:Objective: to investigate the CT features and differential diagnosis of ganglioneuroma and ganglioneuroblastoma. The data of 28 cases of ganglioneuroma and 2 cases of ganglioneuroblastoma confirmed by operation and pathology in our hospital were analyzed retrospectively. Results among 28 cases of ganglioneuroma, 15 cases were located in adrenal area, 6 cases were paraspinal thoracic segment, 2 cases were lumbar spinal area, 4 cases were cervical sheath area, and 1 case was presacral area. The tumor presented as round, round, water-droplet soft tissue mass with clear boundary and smooth margin. In 14 cases, punctate calcification was observed. 16 cases had false foot sign; 24 cases with homogeneous density and 4 cases with heterogeneous density were found to contain fat in 1 case, and slight enhancement in 11 cases presented as flaky flocculent delayed enhancement. 2 cases of ganglioneuroblastoma were located in the adrenal area. Ct findings were irregular soft tissue mass, uneven density, obvious necrosis, cystic change, coarse calcification and uneven enhancement. Conclusion: the CT features of ganglioneuroma and ganglioneuroblastoma have important value in the qualitative diagnosis of ganglioneuroma and ganglioneuroblastoma. The possibility of ganglioneuroblastoma should be considered in peripheral tissue invasion and lymph node metastasis.

【正文快照】： 节细胞神经瘤(ganglioneuroma,GN)与节细胞神经母细胞瘤(ganglioneuroblastoma,GNB)同属外周性神经母细胞性肿瘤,起源于构成交感神经系统的不同成熟程度的神经嵴细胞,由于分化程度不同,生物学表现存在差异。GN由完全成熟的节细胞及其他成熟组织构成,为良性肿瘤;GNB由成熟节细
