CT and MRI Findings of a Transitional Cell Carcinoma Case Located at Sino-nasopharyngeal Junction Sinonazofaringeal Bileşkede Yerleşen Transizyonel Hücreli Karsinomun BT ve MRG Bulgulari

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.
