Abstract：Objective To analyze PET/CT manifestations of laryngeal carcinoma and hypopharyngeal carcinoma and to discuss its diagnostic value. Methods We collected PET/CT findings in 19 patients with laryngeal carcinoma and hypopharyngeal carci-noma proved pathologically from October 2014 to February 2017,and retrospectively analyzed the PET/CT manifestations.Results In this 19 cases,there were 11 cases of laryngeal squamous cell carcinoma,1 case of laryngeal malignant tumors of leaf and 7 ca-ses of squamous cell carcinoma of larynx. PET/CT manifestations presented with laryngeal cavity,epiglottis or pharyngeal soft tis-sue in 10 cases who were complicated with metabolism increased. There were 3 cases of unilateral vocal cord lesions with in-creased metabolism,2 cases of laryngeal cavity wall thickening and increased metabolism,2 cases of unilateral piriform fossa le-sions with increased metabolism,1 case of hypopharyngeal wall metabolism increased,and 1 case was false negative image. The mean maximal standard uptake value(SUVmax) was(13.5 ± 7.1). Conclusion PET/CT has higher diagnostic value of laryn-geal and hypopharyngeal carcinoma,which is worthy of clinical popularization and application.
