[Analysis of MRI and CT manifestations of paranasal sinuses and orbitocranial disorders with secondary exophthalmos].
OBJECTIVE
To study the MRI and CT manifestations of paranasal sinuses and orbitocranial disorders with secondary exophthalmos.


METHODS
MRI and CT scans of 51 patients were examined.


RESULTS
MRI offers more information for evaluation of soft tissue lesions; the cavernous hemangioma and dermoid cyst were found to present rather characteristic images. Whereas in evaluation of lesions involving bony structures and calcifications, CT was superior to MRI.


CONCLUSIONS
CT and MRI may evaluate the tumor location, extension into adjacent areas and are valuable in differential diagnosis of paranasal sinuses and orbitocranial disorder with secondary exophthalmos.
