The location and the cystic content give the best clues in determining the type of laryngocele. 定位及囊内容物是确定喉气囊肿类型的最好的线索。
Ideally a laryngocele can be diagnosed by CT or MR imaging, because the content of the cyst ( i.e.air or fluid) is apparent in these imaging modalities. 理论上一个喉气囊肿可以通过CT或MR诊断,因为囊肿的内容物在这些影像上表现很直观。
MRI Diagnosis in Laryngocele 喉气囊肿的MRI诊断
Among the 6 cases with persistent inspiratory dyspnea, four of them were diagnosed as congenital laryngocele by direct laryngoscope, one case was diagnosed as subglottic stenosis by tracheoscopy and one case was confirmed to be thoracic tracheostenosis when tracheotomy performed. 6例持续性呼吸困难,直接喉镜检查确诊先天性会厌囊肿4例,气管镜检查确诊声门下狭窄1例,气管切开时确诊胸段气管狭窄1例。
Objective To discuss the MRI findings of laryngocele. 目的探讨喉气囊肿的临床和MRI表现。
