CT Evaluation of Squamous Cell Carcinoma of the Nasopharynx

Squamous cell carcinoma is the most common type of neoplasia which affects the mucosa of the upper aero-digestive tract. Nasopharyngeal carcinoma is a unique disease with clinical behavior, epidemiology, and histopathology that is different from that of squamous cell carcinomas of the head and neck. For malignant tumors such as SCC, rapid growth may occur even though there are no previous clinical signs. Enlargement of a cervical lymph node, as the first presenting feature of neoplasia, is not uncommon, particularly with certain “silent” site, such as nasopharynx. Therefore, clinical examination must be complemented by radiological examination for the assessment of size, thickness and depth of the tumor, the degree of bone tissue invasion, and to detect the presence of enlarged lymph nodes. A total of 16 cases of patients were studied using CT, all diagnosed and operated with squamous cancer with localization in the nasopharynx.
