Role of US and Diffusion Weighted MRI in Detection of Thyroid Cartilage Invasion in Patients with Laryngeal Carcinoma

Abstract

ancer larynx is the second most frequent tumor of the head and neck. Consistent with a large cases series lately published by (Ciolofan et al.,2017) the most of larynx malignancies (i.e., over 98%) are well-differentiated squamous cell carcinomas, whilst chondrosarcomas, leiomyosarcomas and melanomas just account for 2%−5% of all laryngeal cancers. Among squamous cell carcinomas, the well and moderately differentiated types slightly prevail over poorly differentiated tumors, accounting for 43.5% and 41.5% of all patients, respectively. The bigger amount of laryngeal cancer cases arise from the glottic region (i.e., approximately two-third), then the supraglottic area (about 30%), while transglottic and purely subglottic tumors are usually less common.
