外周节细胞神经瘤CT表现特点分析

Peripheral ganglioneuroma:the analysis of CT findings

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. Methods Combining the clinical manifestations and pathlolgical characteristics, the CT im-ages of seven ganglioneuromas were analyzed retrospectively, CT plain scan and enhancement scan in 7 patinents. Results Among 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 calcifications （3 cases）. Conclusion Ganglioneuroma has some specific imaging features ,the combination of CT findings with clinical information are helpful for its diagnose and differential diagnosis.
