  		Fig. 1A —65 year-old woman with several-year history of hoarseness and dysphagia. Sagittal unenhanced T1-weighted MR image shows posterior submucosal mass in interarytenoid region (arrows, A) that reveals hyperintensity on axial T2-weighted image (arrows, B) and avid enhancement on fat-saturated gadolinium-enhanced T1-weighted image (arrows, C).
