To study the pathological characteristics, CT and clinical appearances of communicans craniorbita tumors So as to improve understanding and diagnostic level of such tumors. Materials and Methods: thirty - six patients with perceived or high doubted lesion in Nasal vavity and Nasal Sinuses wre examined and performed axial and coronal scan, with and without intravenous injection by CT on head. Results : All 36 cases were confirmed with patholgy including thirteen squamocarcinoma, Seven adenocarcinoma, Six cystadenocarcinomas, Two inverted papilloma, Seven nasalpolyp, Two nasosinusitis. The detectability of tumor was 100% (28/28), accuracy was 93. 3% (26/28). Conclusion : CT could accurately display location, exten and degree of the lesion.
