Contrast-enhanced CT of the paranasal sinuses in axial plane and bone window.
FINDINGS:
There is a lobulated, expansile lytic lesion of left maxilla with a predominantly lucent center and peripheral calcifications. The lesion is centered at the left maxillary alveolus and is associated with a large soft tissue component which shows mild heterogeneous contrast enhancement. The lesion abuts the left inferior orbital wall, with no gross invasion into the orbit. The roots of the left maxillary pre-molars and molars are involved by the mass. There is effacement of the left oral cavity and left nasal passage.

Axial fused PET-CT images of the paranasal sinuses and Coronal PET image of the whole body (presented only the head portion).
FINDINGS:
There is a moderately FDG-avid mass (index SUVmax was 9.7) arising from left maxilla. No other abnormal focus of increased FDG-uptake is seen in the coronal PET image.
