title: Computer-assisted tomography: sinus lesions with orbital involvement.
abstract: Computer-assisted tomography (CAT) is superior to other roentgenographic modalities in evaluation of paranasal sinus lesions whenever extension into the orbit is suspected. CAT not only demonstrates the orbital involvement, its location, and extent, but also the nature of the sinus lesion. Conclusions based on 43 cases of paranasal sinus lesions with orbital involvement are presented. The entities include sinusitis and orbital cellulitis, mucocele, polyposis, ossifying fibroma, fibrous dysplasia, cylindroma, osteoblastoma, lymphoma, carcinoma, and rhabdomyosarcoma.
