目的:分析节细胞神经瘤的CT表现,以提高对该病的认识,提高对该病诊断的准确性。方法:回顾性分析经手术病理证实的节细胞神经瘤7例,男4例,女3例,年龄27~59岁,平均42岁。7例患者均行CT扫描,包括平扫加增强扫描5例,CT平扫2例。结果:7例肿瘤中,2例位于纵隔;2例位于肾上腺;3例位于腹膜后间隙。7例肿瘤边缘清晰,呈椭圆形1例、类圆形5例、不规则形1例。CT平扫表现为肿瘤呈均匀低密度6例、混杂密度1例;增强扫描后呈轻、中度强化4例、不强化1例;伴有钙化4例。结论:CT有助于提高对节细胞神经瘤诊断的准确性,并可通过显示肿瘤与周围血管及器官的关系,为临床和手术提供更多的参考信息。
Objective: To analyze the CT manifestations of ganglioneuroma in order to improve the understanding of the disease and improve the accuracy of the diagnosis of the disease. Methods: Seven cases of ganglioneuroma confirmed by surgery and pathology were retrospectively analyzed. There were 4 males and 3 females, aged from 27 to 59 years with an average of 42 years. Seven patients underwent CT scan, including plain scan and enhanced scan in 5 cases, CT scan in 2 cases. Results: Of the 7 tumors, 2 were located in the mediastinum, 2 in the adrenal gland and 3 in the retroperitoneal space. Seven cases of tumor edge clear, oval in 1 case, 5 cases of circular, irregular in 1 case. In CT plain scan, there were 6 cases with uniform low density and 1 case with mixed density. Four cases were mild and moderate enhancement after intensive scanning, and one case without enhancement. There were 4 cases with calcification. Conclusion: CT can help to improve the accuracy of diagnosis of ganglioneurocytoma and can provide more reference information for clinical and surgical operation by showing the relationship between the tumor and the surrounding blood vessels and organs.
