摘要
目的：比较颈部神经鞘瘤的CT表现及相应的组织病理切片，了解其CT表现的病理学基础。方法回顾性分析我院2003年1月～2012年12月期间经术后病理证实的颈部神经鞘瘤且资料完整30例并观察其CT表现与术后病理结果进行比较。结果 CT平扫表现为均匀等密度、稍低密度（与颈部肌肉对比）肿块者其增强扫描呈轻度均匀强化（13例）；平扫表现为不均匀等密度、稍低密度肿块，伴中央点状或片状更低密度区者其增强扫描呈轻度或明显强化（17例），中央更低密度区无明显强化。不同细胞成分可形成不同的CT表现，增强区与Antoni A 区存在有关。结论颈部神经鞘瘤特殊的CT表现与病理改变有关，有利于其正确诊断。
Objective To compare the CT features of cervical neurilemmoma in correlation with pathologic tissue slices and to investigate the pathologic basis of those findings. Methods Forty-six patients with pathological diagnoses of cervical neurilemmoma from January 2003 to December 2012 were reviewed retrospectively. Among these patients, 30 were scanned with enhancement. The manifestations of CT scans were compared with the results of pathology. Results Thirteen of 30 showed homogeneous isodensity or slightly low density （compared with neck muscle） used CT was homogeneous enhanced slightly after enhancement. 17 of 30 appeared as heterogeneous isodensity or slightly low density with a central point or flake lower density area showed mild or significant enhancement except for the central lower density areas. Different cell components form different CT performance, and the enhance area was associated with Antoni A area. Conclusion The CT manifestations of cervical neurilemmoma are related with pathologic changes, and it was conductive to the diagnosis.
