Sinonazal Bölge Benign Kemik Tümörlerinin Radyolojik Değerlendirmesi

Öz

Amaç: Sinonazal bölgedeki benign kemik kitlelerini, sinonazal bölge ve komşu yapılarla ilişkisinin radyolojik olarak değerlendirilmesi.

Gereç-yöntem: Sinonazal bölgeden 2010-2016 yılları arasında elde edilen çok kesitli bilgisayarlı tomografi (ÇKBT) ve manyetik rezonans görüntüleme (MRG) bulguları retrospektif olarak değerlendirildi. Radyolojik bulgulara dayanarak, büyüklükleri nedeniyle nadir görülen 41 olgu, histopatolojik özellikler ve lokalizasyonları çalışmaya dahil edildi.

Bulgular: 41 olgunun 22'inde osteoma, 16'sında fibröz displazi, diğerlerinde anevrizmal kemik kisti, enkondrom ve kahverengi tümör vardı.

Sonuç: Sinonazal bölgenin iyi huylu kemik tümörlerini görüntülerken, ÇKBT ve MRG en sık kullanılan yöntemlerdir. Radyografi, bazı durumlarda bir lezyonun varlığını gösterebilir, ancak lezyonun doğasını ve lezyon ile komşu yapılar arasındaki ilişkileri belirlemekte yetersizdir

Radiological Evaluation of Benign Bone Tumors of Sinonasal Region

Öz

Aim: To evaluate radiologically the benign bone masses in the sinonasal region and their relationship with adjacent structures.
Methods: Multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) of the sinonasal region were evaluated retrospectively between 2010-2016. Based on radiological findings, 41 cases rarely seen due to 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 tumors 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 determine the nature of the lesion as well as the relations between the lesion and the neighboring structures.
