目的：探讨节细胞神经瘤的CT表现特点，以提高对该病的认识。方法回顾性分析经病理证实的7例节细胞神经瘤的CT平扫及增强扫描特点（病变部位、大小、边界、钙化、强化特点）。结果7例节细胞神经瘤中，病灶位于后纵隔者2例，位于腹膜后间隙者2例，位于右侧肾上腺、左侧咽旁间隙及盆腔内者各1例。所有病灶均边界清楚，圆形或椭圆形。CT平扫表现为肿瘤呈均匀低密度6例、混杂密度1例；伴有斑点状及砂粒样钙化3例；增强扫描后，呈轻、中度强化3例、不强化4例。结论节细胞神经瘤CT表现有一定的特点，结合临床症状有助于其诊断和鉴别诊断。“,”Objective To investigate the CT findings of ganglioneuroma for improving its recognization and diagnostic accuracy.MethodsCombining the clinical manifestations and pathological characteristics, the CT images of seven ganglioneuromas were analyzed retrospectively with CT plain scan and enhancement scan in 7 patients.ResultsAmong 7 patients with ganglioneuroma, the lesions in the posterior mediastinum (2 cases), in the retroperitoneal space(2 cases), in the right adrenal gland, the left parapharyngeal space and the pelvis (each 1 case). On plain scan, the lesions was of homogeneous low density (6 cases) or inhomogeneous density (1 case). On enhanced scan, there were mild or moderate enhancement (3 cases) and no enhancement (4 cases), with speckled and sand-like calciifcations (3 cases).Conclusion Ganglioneuroma has some speciifc imaging features, the combination of CT ifndings with clinical information is helpful for its diagnosis and differential diagnosis.
