Hassem,

Difficult to judge without viewing the entire volume, especially in coronal sections where we would have a better viewing of the osteomeatal complex area.  I certainly agree that this is inflammatory/infectious in nature.  There is no air in the images, suggesting mucocele - however, there is a lot of sinus not shown.  This thick bone may represent osteomyelitis, often seen adjacent to a mucocele or to chronic severe sinus infection.  I think malignancy is quite unlikely as there is no frank bone destruction that I can see.

Cheers,

Dear Colleagues.
I would like your input on the following images of a maxillary sinus: 65 Y-O male referred for evaluation of an impacted third molar.
The left maxillary sinus is completely obliterated, and the cortical bone appears to be getting more thickness. With no relevant history, I am considering a Sinusitis. Mucocele or low grade malignant process less likely.
Any other suggestions?

For comparison, I am adding also a coronal image of a patient with a confirmed Acute sinusitis.
