Diagnostic procedures in nasopharyngeal illness.

The nasopharynx contains a wide variety of different cell types. Therefore, many kinds of lesions can occur in this area, ranging from embryologic abnormalities to benign and malignant neoplasms. The challenge to the radiologist is to describe the extent and localization of inflammation, benign, and malignant tumors. The diagnostic procedures in these cases include flexible or rigid fiberoptic clinical examinations. Pantomography and plain film studies are usually done as part of the initial examination, and CT replaces pluridirectional tomography for all questions about compact bone. Soft tissue extent of lesions is better shown on MR imaging. New scientific experiences in diagnosing lesions of the area of the nasopharynx are presented.
