Purpose: The purpose of our study was to accurately visualize and measure the normal anatomy of pterygopalatine fossa and its communications on multi-detector row CT with thin-section HRCT (0.5mm) and multiplanar reconstruction and curved planar reconstruction technologies, so as to obtain credible and comprehensive information for clinical management and basic research.

The CT and MRI results showed soft tissue disease focus was found and its boundary was not clear, enhancement CT and MRI scanning showed 8 and 11 cases had low and middle degrees enhancement,respectively. The pathological changes in 22 cases often be outside the nasal cavity and paranasal sinus but infringed upon the pterygopalatine fossa, orbit.

Results and Conclusions （1）MRI is better than CT to show the lesion of cerebellar fossa and brain stem.（2）Late radiation encephalopathy may be the result of immunal response to the damage of brain tissue and blood vessel after radiotherapy（3） 18 F-FDG-PET is a effective screenage examimation to diagnosis late radiation encephalopathy.（4）To some degree,the symptoms of the patients were alleviated after therapy with dexamethasome,mannital and vitamine B,etc.Late radiation encephalopathy ought to be given priority to prevention and treated vigorously as soon as possible.
