NASOPHARYNGEAL CARCINOMA - COMPUTED TOMOGRAPHIC IMAGING OF 4 CASES

Nasopharyngeal carcinoma occurs with great frequency in Asia. It is an infiltrative tumor that often produces no symptoms early in its cours e. However, the proximity of the nasopharynx to the nasal cavity, eust achian tubes, masticatory muscles, and cranial nerves can allow extens ion of the lesion into these structures, resulting in numerous maxillo facial abnormalities. Computed tomography is effective in imaging the development of nasopharyngeal carcinoma in the nasopharynx as well as the subsequent spread of the neoplasm to adjacent areas. Four cases of nasopharyngeal carcinoma are presented in which computed tomography p rovides an accurate assessment of the extent of the tumor and allows c orrelation with clinical manifestations.
