    Abstract:
    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. CONCLUSION: 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.
