Incidental finding in a 34 year-old male of the Right Zygomatic bone moderately well defined opacity 8 x 15 x 27 mm. The bone is sclerotic with a small oblong central low density region and is continuous with surrounding bone.
The zygomatico-temporal and zygomatico-maxillary sutures are visible. The bone density varies slightly and is not uniform.
There is an increase in size compared to the left zygomatic bone. Differential diagnosis includes 1) fibrous dysplasia, 2) trauma, 3) osteoma.
In the absence of signs or symptoms no further investigation recommended.
