节细胞神经瘤的 CT、MRI 影像表现与病理对照研究

目的：研究节细胞神经瘤的CT和MRI表现并进行病理学对照。方法对经手术病理证实的12例节细胞神经瘤患者的临床病理资料进行回顾性分析，所有患者均进行CT和MRI检查，并与病理学结果进行对照分析。结果病灶大小为（4．7±1．2）cm，CT平扫为不均匀或均匀的低密度；MRI平扫中，T1WI均呈现不均匀的低信号，T2 WI均呈现不均匀的等高信号，中间有部分条状的低信号。12例进行MRI增强扫描时，不强化的有4例，轻度强化的有3例，均匀渐进性强度强化的有2例，不均匀渐进性强化的有3例，边缘环状强化的有1例，与CT增强扫描结果一致。结论 CT和MRI作为检测节细胞神经瘤的影像学手段，其表现具有一定的特征性，并在很大程度上能够反映出肿瘤的形态、大小及组织成分，与病理中肿瘤所富含的大量黏液基质具有一定的关系。

Comparative study of CT,MRI images and pathological findings of ganglioneuroma

Objective To study the CT and MRI findings of ganglioneuroma and compare with pathology . Methods Clinical data of 12 patients with ganglioneuroma confirmed by surgical pathology were retrospectively ana -lyzed.All patients underwent CT and MRI , and the results were compared with pathological results .Results The average size of the lesion was （4.7 ±1.2）cm,CT scan was uneven or uniform density.In MRI plain scan,T1WI showed heterogeneous low signal ,T2 WI showed uneven contour signal ,the middle part of the strip of low signal .12 cases received enhanced MRI scan ,there were four cases of non-enhanced,mild enhancement in 3 cases,uniformity progres-sive strength enhanced with two cases ,uneven progressive enhancement in 3 cases,there was 1 patient with edge of the annular reinforcing ,in accordance with CT scan results .Conclusion When CT and MRI used as the detection means of ganglioneuroma ,its performance has a certain characteristic ,and that reflects in large part the tumor shape ,size and tis-sue composition .And pathological tumor is rich in a lot of mucus matrix has a certain relationship .
