目的探讨喉结核CT、MRI表现特点。方法搜集9例经手术病理证实的喉结核患者的CT(n=7)和MRI(n=2)资料,分析其CT和MRI表现。结果 9例患者中,弥漫型7例,局灶型2例。病变主要表现为声门及声门上区、咽后壁软组织弥漫性、对称性或不对称增厚。CT平扫密度略低,MRI呈稍长T1、稍长T2异常信号,增强晚期表现为黏膜面呈线状强化,所有患者均无喉软骨破坏及喉外侵犯。结论喉结核的CT、MRI表现有一定特征性,结合胸片及肺部CT有助于正确诊断。
Objective To investigate the CT and MRI features of laryngeal tuberculosis. Methods The CT (n = 7) and MRI (n = 2) data of 9 patients with pathologically confirmed laryngeal tuberculosis were collected and their CT and MRI findings were analyzed. Results Of the 9 patients, 7 were diffuse and 2 were focal. Lesions mainly for the glottis and supraglottic area, soft posterior pharyngeal diffuse, symmetrical or asymmetric thickening. CT scan density slightly lower, MRI showed a slightly longer T1, slightly longer T2 anomalous signal, enhanced late manifestations of mucosal surface was linear enhancement, all patients without laryngeal cartilage damage and throat violations. Conclusion The CT and MRI manifestations of laryngeal tuberculosis have certain characteristics. Combined with chest radiograph and pulmonary CT, it is helpful to correct diagnosis.
