Based on radiological findings, 41 cases rarely seen dueto their size, histopathologic features and localizations were included in the study.Results: Twenty-two of 41 cases had osteoma, sixteen had fibrous dysplasia, others had aneurysmal bone cyst,enchondroma and brown tumor.Conclusion: When imaging benign bone tumours of sinonasal region, MDCT and MRI are the frequently used modalities. Radiography may show the presence of a lesion in some cases but is insufficient when it is aimed to determinethe nature of the lesion as well as the relations between the lesion and the neighbouring structures.eninfo:eu-repo/semantics/openAccessArticle11391810.17944/mkutfd.644305426085
