目的评价纵隔神经源性肿瘤的影像学表现。方法对20例经过手术及病理证实的纵隔神经源性肿瘤进行回顾性分析,所有病例术前均行CT及MRI平扫及增强扫描。结果根据病理学分3型:①外周神经肿瘤13例;②交感神经及神经节肿瘤5例;③副交感神经节组织的肿瘤2例。根据病灶强化特征分为5型:①环形强化型;②均匀强化型;③不均匀强化型;④无强化型;⑤分隔样强化型。结论熟悉纵隔神经源性肿瘤的影像学特点,对诊断与鉴别诊断有重要价值。
Objective To evaluate the imaging findings of mediastinal neurogenic tumors. Methods Twenty cases of mediastinal neurogenic tumors confirmed by surgery and pathology were retrospectively analyzed. All patients underwent CT and MRI plain and enhanced scanning before operation. Results According to the pathological type 3: ① 13 cases of peripheral nerve tumors; ② 5 cases of sympathetic and ganglion tumors; ③ 2 cases of parasympathetic ganglion tumor. According to the characteristics of the lesion is divided into 5 types: ① annular enhanced; ② uniform enhanced; ③ uneven enhanced; ④ no enhanced; ⑤ separated like enhanced. Conclusion The familiar imaging features of mediastinal neurogenic tumors have important value in diagnosis and differential diagnosis.
