CT and MRI Findings of a Transitional Cell Carcinoma Case Located at Sino-nasopharyngeal Junction

Öz

Nonkeratinizing carcinoma (transitional cell carcinoma) accounts for 1 to 20% of carcinomas of the sinonasal tract. Most of transitional cell carcinomas develop de novo, but a few may arise from preexisting inverted papillomas. Although histopathological findings of transitional cell carcinomas are well documented in the literature, detailed information on imaging findings is scarce. In the present study, CT and MRI findings of a de novo developed transitional cell carcinoma located at sino-nasopharyngeal junction are presented

Sinonazofaringeal Bileşkede Yerleşen Transizyonel Hücreli Karsinomun BT ve MRG Bulguları

Öz

 Nonkeratinize karsinom (transizyonel hücreli karsinom) sinonazal trakt karsinomların %1-20’sini oluşturur. Tranzisyonel hücreli karsinomların çoğu de novo gelişir fakat altta yatan inverted papillomalardan da gelişebilir. Her ne kadar transizyonel hücreli karsinomların histoptolojik bulguları literatürde iyi tanımlanmış olsa dagörüntüleme bulguları hakkında yeterli very yoktur. Bu çalışmada sinonazal bileşkeden de novo gelişmiş bir transizyonel karsinomun BT ve MRG bulguları sunulmaktadır.
