Abstract (2. Language): 
Purpose: İn this study contrubitions of computed tomography (CT) and magnetic resonance imaging (MRI) were researched in the diagnosis of benign paranasal sinüs (PNS) lesions. Materials and methods: According to the clinical findings, betvveen January 2001-February 2004. 30 cases have been studied who vvere thought to have benign lesions belonging to nasal cavity, PNS or neighboring structures. CT and MRI studies are made to the ali case. Inner structure characteristics, locations and radiological apperarances coursing pathologıcal diagnosis of lesions in CT and MRI have been assessed. Results: The hıstopathological diagnoses of lesions vvere mucocele (8j. odontogenic cysts (4j, fıbrous dysplasia (3), inverted papilloma (2j, hemangioma (2), menengioma (2), chondroma (2J, schvvannoma, osteo-ma, osteochondroma, paget disease, amelobiastom, giant celi tumor, central giant celi granuloma. When assessed according to pathological results. sensitivity of CT and MRI vvere found to be 86.6% and 83.3% respectively İn 3 cases shovving radiological malign feature (I giant celi tumor, 2 inverted papillomasj the correct diagnosis vvas made histopathoiogically. Conclusion: CT is an effective method to show bone expansion and destructions, tumors origi-nated from bone, and intratumoral calcifıcations. MRI offers better the İnner structures of cystic lesions, intratumoral hemorhages and differentiation of tumor from inflammation. Therefore. CT and MRI should be used jointly in the evaluation of the PNS lesions.

Amaç: Bu çalışmada, benign paranazal sinüs (PNS) lezyonlannın tanısında bilgisayarlı tomografi (BT) ve manyetik rezo¬nans görüntülemenin (MRGj katkıları araştırıldı. Gereç ve Yöntem: Ocak 200! - Şubat 2004 tarihleri arasında klinik bulgularına göre nazal kavile. PNS veya komşu yapılara ait benign lezyon olduğu düşünülen 30 olgu incelendi. Olguların tümüne BT ve MRG incelemeleri yapıldı. BT ve MRG'de lezyonların iç yapı karakteristikleri, yerleşim yerleri ve patolojik tanıya giden radyolojik görünümleri değerlendirildi. Bulgular: Histopatolojılerine göre lezyonlar; mukosel 8. odontojenik kist 4, fibröz displazi 3, invertedpapillom 2, hemanjiom 2, menenjiom 2. kondrom 2, şıvannom I, osteom I, osteokondrom I, paget hastalığı I. amelobiastom I. dev hücreli tümör i, santral dev hücreli granülom l adet idi. Patolojik sonuçlara göre değerlendirildiğinde BT ve MRG'nin duyarlılıkları sırasıyla %86.6 ve %83.3 olarak bulundu. Radyolojik olarak malign özellik gösteren 3 olguda (I dev hücreli tümör. 2 inverted papillom) doğru tanı histopatolo-jik olarak kondu. Sonuç: BT. kemik ekspansiyon ve destrüksiyonlarını. kemik kaynaklı tümör/eri ve tümör içi kalsifıkas-yonları göstermede etkin bir yöntemdir. MRG ise kistik lezyonların iç yapılarını, tümör İçi hemorajileri ve tümör-infla-masyon ayrımını daha iyi gösterir. Bu yüzden benign PNS lezyonlarını değerlendirmede BT ve MRG birlikte kullanılmalıdır.
