Computerized tomography in conditions concomitantly involving the orbits and the paranasal sinuses

Forty-three patients with computerized tomographic (CT) findings demonstrating concomitant orbital and paranasal sinus involvement are presented. Exophthalmos was the most common presenting symptom. Ethmoid and maxillary sinuses were most commonly affected. CT findings were of help in evaluating the extent of the various disease processes and are mandatory for treatment planning. Attention is drawn to the common association of paranasal lesion and ophthalmic manifestations. The combination of clinical presentation and radiological findings might indicate certain etiologies.
