Analysis of CT Imaging in Nasopharyngeal Carcinoma

  • Objective:To recognize CT signs of nasopharyngeal carcinoma (NPC) profoundly. Methods: Nasopharynx axial CT scans were performed in 69 cases of NPC proved pathology. Their CT findings before radiotherapy were analyzed in details. Results: The seequence of CT findings in NPC was thickening of the lateral wall of nasopharynx (87.0%), narrowing of parapharyngeal space (PPS)(68.1%), thickening and compactness of the soft-tissue medial to the styloid process (59.4%). involvement of posterior naris and nasal cavity (42.0%), and bone destruction of skull base (37.7%). The rate of the other abnormal finding was low. Conclusions:Involvement of lateral wall of nasopharynx could be seen in most NPC. After breakthrough the pharyngobasilar fascia, the tumor usually invades PPS and the soft-tissue medial to the styloid process.
