Presentation
Left proptosis.
Patient Data
Left frontal sinus expansile mass lesion eliciting persistent dark signal on all pulse sequences with no post contrast enhancement. The lesion shows exophytic intra-orbital extension displacing the left eyeglobe and left superior rectus/superior levator palpare superiosis muscle complex with subsequent proptosis. The lesion also shows small intracranial extension elevating the left frontal lobe.
Radiological findings are suggestive of left frontal sinus osseous lesion, likley osteoma.
The lesion appears densly calcific on CT exam, consistnt with osteoma.
Case Discussion
Paranasal sinus osteomas are common benign tumors, usually found incidentally. They might be symptomatic if they exerted mass effect as in this case or obstructed the drainage of the paranasal sinuses.
