UNASSIGNED: Computed tomography (CT) is commonly used to investigate @entity135 in @entity235 , however little information is available for lesions of the pharyngeal area. The purpose of this multicentric, retrospective, cross-sectional study was to describe the CT findings in a sample of @entity235 with pathologically confirmed @entity5 and determine whether any CT features allowed differentiation of @entity5 type. Location of lesions, size and shape, margins, relationship with surrounding structures and vessels, attenuation characteristics and enhancement pattern, regional lymph node changes, and presence of @entity3 were recorded by three observers (1 DECVDI). The effect of final diagnosis on each CT feature was tested. A total of 25 @entity235 were included: 15 with @entity189 , five @entity242 , four @entity320 , and one @entity706 . The oropharynx and laryngopharynx were more frequently involved. Among @entity5 groups, lesions were of similar size, irregularly shaped, had ill-defined margins, and had moderate-to-marked heterogeneous contrast enhancement. Lysis of hyoid bones was recorded in two @entity189 and @entity432 occurred in one case. Marked medial retropharyngeal lymphoadenomegaly was recorded in 11 of 14 @entity189 , in all @entity242 and in two of four @entity320 . The single @entity706 case showed ill-defined thickening of the oropharyngeal and laryngeal wall with retropharyngeal and mandibular lymphadenomegaly. Lung metastases were found in two of five @entity242 and two of four @entity320 . Findings from the current study did not support the hypothesis that CT features could be used to predict @entity5 type in @entity235 . However, CT was helpful for determining mass extension, lymph node involvement, and distant metastatic spread.
