Olfaktör nöroblastoma (esthesioblastoma) radyolojik bulguları

Olfaktör nöroblastoma (ONB), diğer bir isimle esthesi- oblastoma, olfaktör epitelyumdan köken olan, genelliklenazal kavite olfaktör bölgede ve ön kafa tabanında yeralan nadir malign bir neoplazidir. Bugüne kadar literatürde az sayıda vaka bildirilmiştir. ONB tanısı ve sınıflandırması için ayrıntılı radyolojik ve histopatolojik inceleme gereklidir. Özellikle lokal seyreden tümörlerde prognoz iyi seyirli olup bölgesel ve uzak metastaz kötü prognozbelirtileri olarak kabul edilmiştir. Cerrahi ve radyoterapi günümüzdeki başlıca tedavi yöntemleridir. Biz buradaONB saptanan 64 yaşındaki erkek olgunun X-ray grafi, B Mod-Doppler Ultrason (US) ve Bilgisayarlı Tomografi (BT) bulgularını sunduk.

Radiologic findings of olfactory neuroblastoma (Esthesioblastoma)

Olfactory neuroblastoma (ONB) also known as esthesio- blastoma is a rare malignant neoplasm originating from olfactive epitelium, usually locate in the olfactory region of the nasal cavity and anterior skull base. Few cases have been published in the literature yet. Detailed radiologic and histopathological examination is necessary for diagnosis and staging ONB. Prognosis is favorable especially for locally advanced tumors; regional and distant metastasis has been accepted as indicators of poor prognosis. Surgery and radiotherapy are the main therapeutic modalities in use today. We reported the x-ray graphic, B Mod-Doppler Ultrasound (US) and Computed Tomography (CT) findings of 64 years-old male with ONB in this presentation.
