鼻腔肿块性病变的CT诊断价值

目的探讨鼻腔肿块性病变cT影像特点，进一步提高其诊断水平。方法搜集经病理证实和CT检查的鼻腔肿块性病变96例，其中男56例，女40例，年龄2862岁。CT平扫52例，CT平扫＋增强扫描44例，比较分析良恶性肿块的CT表现。结果本文96例，其中良性肿块76例，骨质破坏者6例；恶性肿块20例中，骨质破坏者19例，经x^2检验，x=62．37，P=0．000，有高度显著意义。76例良性肿块，伴有骨质吸收者12例；而20例恶性肿块中，均未见有骨质吸收，经x^2检验，x=3．61，P=0．057〉0．05，两者差别无显著意义。结论CT可对多数鼻腔的肿块做出正确诊断，有利于指导手术方案的制定。

The Value of CT Diagnosis of Nasal Cavity Mass Lesions

Objectlve To explore CT imaging features of nasal cavity mass lesions, and further improve the diagnostic level. Methods Collected 96 cases of nasal mass lesions were confirmed by pathology, there were 56 cases of male and 40 cases of female, age of 28 to 62 years old. There were 52 cases of CT plain scan, and plus contrast CT scan in 44 cases. CT findings of the benign and malignant mass in nasal cavity were analyzed contrastly. Results In 76 cases of benign tumor, there were 6 cases associated with bone breaker; in 20 cases of malignant tumors, there were 19 cases associated with bone destruction; by x 2 test, x = 62.37, P ： 0. 000, there was statistical disparity between these tow groups. In 76 cases of benign tumor, there were 12 cases associated with bone resorption; in 20 cases of malignant tumors, no case associated with bone loss; by x 2 test, x = 3.61, P = 0.057〉 0.05, there was not significant disparity between these tow groups. Conclusion Most of the nasal cavity mass can be exactly diagnosis with CT scan, and it is helpful to guide the development of surgical programs.
