Abstract
Objective To study the CT characteristics of nasopharyngeal cancer of original position and the invaded neighborhood structures. Methods 42 patients with nasopharynx cancer were confirmed by pathology. The rule of nasopharyngeal cancer of original position and the invaded neighborhood structures were retrospectively studied. Results In 42 patients, the original position of the nasophargngeal cancer was located in the lateral pharyngeal wall of 29 cases (69.0% ) , the top posterior wall of 13 cases (31.0% ). And the parapharyngeal space was invaded in 34 cases (81. 0% ). In the 34 cases of parapharyngeal space invasion, the lymph metastasis rate was 82.4% (28/34) , which was significantly higher than 37.5% (3/8) of the non-parapharyngeal space invasion (P=0.02). And the positive symptom rate of headache and cranial nerve sign was 87.5% (14/16) in the patients with skull base invasion, which was higher than 19. 2% (5/26) of the non-skull base invasion. Conclusion The lateral pharyngeal wall is the most common position that the nasopharyngeal cancer occurs, and the top posterior wall is the next. Cervical lymph node metastasis is related with the degree of parapharyngeal space involvement. Positive symptoms of headache and cranial nerve sign are important indications of skull base invasion.
