Abstract:
Objective To investigate the value of CT and MRI in diagnosing nasopharyngeal angiofibromas.Methods 18 cases of nasopharyngeal angiofibromas were retrospectively analyzed including the location, density ,signal intensity, extension of tumors and changes of surrounding bones.Results 16 cases located in the area around sphenopalatine foramen. 6 cases exhibited homogeneous density on CT scans(6/11 cases) and 12 cases displayed inhomogeneous signal intensity on MR scans(12/14 cases). All the Fourteen MRI examinations revealed vice signal by vessels, inhomogeneous enhancement and extensive invasion along the foramina or fissures.Conclusion MRI not only determines the location and traces out the extension of nasopharyngeal angiofibroma more exactly, but also displayes its diagnostic signal fashion. Namely MRI has greater value in diagnosing this tumor than CT.
