History

A 19-year-old Asian male presented with facial pain of 2 1/2 months duration that was believed to be dental-related. Root canal therapy and multiple extractions failed to alleviate the patient’s discomfort. Subsequent CT images demonstrated an extensive mass in the left maxillary sinus.

Radiographic Features

Computed tomography of the paranasal sinuses using Landmarx protocol was performed using axial images without the administration of intravenous contrast material. Axial, sagittal and coronal reformatted images of the paranasal sinuses were obtained. CT images revealed opacification of the left maxillary sinus by a lesion with a calcific rim. There were additional areas of punctate calcifications within the lesion which represented matrix mineralization (Fig.  1). The lesion induced moderate expansile remodeling of the left maxillary sinus and mucosal thickening surrounding the lesion (Fig.  2). There were additional mucosal thickenings of the nasal cavity, ethmoid sinus, and...
