STUDY ON COMPUTED TOMOGRAPHY FINDINGS OF NASOPHARYNGEAL CARCINOMA
Objective: This study aims to characteristics of CT imaging in the diagnosis of nasopharyngeal carcinoma. Materials and method: 62 patients were hospitalized in Hue Central Hospital from May 2009 to May 2010. These patients were passed CT scanner and confirmed the nasopharyngeal carcinoma on pathology result. Cross-sectional study. Results: Site of tumor on lateral pharyngeal recess is 79.03%; all tumor enhanced by contrast medium and heterogenuos (90,32%); hypervascular (79,03%); intratumoral necrosis (14,52 %); abnormal Rosenmuller fossa (70,97%), Eustachian (64,51%); extending into the pterygomaxillary fossa (56,45%), the nasal cavity (33,87%); skull base erosion (14,52%), invades maxillary sinuses (12,90%), pterygomaxillary process (11,29%). Conclusion: Through this study, we found that CT imagings have many advantages in detecting nasopharyngeal tumors, and tumor position. CT technich is also a good assessment for invasive structures of anatomy around the nasopharynx, especially with the high sensitivity in detecting invasive bone and sinuses.
