title: MRI and 18F-FDG PET/CT of Laryngeal Cartilaginous Tumor.
abstract: Cartilaginous tumors of the larynx are uncommon neoplasms that sometimes mimic laryngeal cancers. There has been no report of F-FDG PET/CT for the evaluation of laryngeal cartilaginous tumors. We reported 3 cases of laryngeal cartilaginous tumors with the image findings, including CT, FDG PET/CT, and MRI and reviewed literatures. We concluded that the combination of a very high-signal mass on T2-weighted magnetic resonance images and lower FDG uptake might be diagnostic image characteristics for distinguishing laryngeal cartilaginous tumor from laryngeal cancer.
