Abstract:
Laryngeal schwannoma is extremely rare. We report the CT and MRI findings of a case occurring in a 65-year-oldwoman, and describe the pathologic correlation. Pre-contrast CT scanning revealed a right supraglot-tic mass witha slightly hyperdense central part and a hypodense peripheral part. Post-contrast CT scanning re-vealed anenhanced hyperdense central part and a rim-like hypodense peripheral part. The density of the pe-ripheral part waslower than that of muscle. The mass showed homogeneous low signal intensity on T1-weighted MR images, homogeneoushigh signal intensity on T2-weighted MR images, and an enhanced high signal intensity central part and a lowsignal intensity peripheral part on gadolinium enhanced T1-weighted images. The enhanced central part correlatedwith Antoni A areas and the peripheral part, showing low attenuation, correlated with Antoni B areas.
