1. Malignancy in right maxillary sinus: Medical referral indicated
The right maxillary sinus is almost completely opacified by a soft tissue mass, and extensive lytic bone loss involves the antral walls and the right posterior maxillary alveolar process. The alveolar crest is lost within the molar region, and no signs of bone grafting material or reparative bone formation are noted in the extraction sites. The right inferolateral nasal wall is thinned and medially displaced, and partial opacification of the right inferior nasal meatus is apparent. The right orbital floor remains intact.
This radiographic appearance is most consistent with a malignant process originating within the right maxillary sinus. Immediate medical referral for further management is indicated.
Additional images of right posterior maxilla
These images demonstrate the extensive area of lytic bone loss associated with the right posterior maxillary alveolar process, which extends through the crestal bone.
2. Exposed buccal threads on implant 12
The buccal threads overlying the implant at site 12 are not embedded within bone. The remainder of the implant appears to be osseointegrated.
3. Mild mucositis in the left maxillary sinus
Mild mucositis is present within the left maxillary sinus. This is a non-significant incidental finding.
4. Intracranial calcification of internal carotid arteries
Extensive calcifications are visible lining the walls of the cavernous and ophthalmic segments of the right and left internal carotid arteries. These findings may represent signs of atherosclerosis. The significance of this finding cannot be determined based on CBCT imaging alone.
5. Mild cervical degenerative joint disease
Small osteophytes and mild subchondral sclerosis are present in the articular regions of the atlas and dens of the cervical vertebrae. This is a common incidental finding with no clinical significance that is suggestive of mild cervical degenerative joint disease.
6. Left palatine tonsilloliths
Tonsilloliths are present in the left palatine tonsil. This is an incidental finding with no clinical significance.
