Presentation
Incidental finding.
Patient Data
The right first superior molar tooth shows signs of decay and a cavity filled with soft tissue content is observed in its root. The adjacent right maxillary sinus is obliterated.
MRI Brain performed for other reasons shows signs of acute sinusitis within the right maxillary sinus characterized by mucosal thickness and sinus obliteration by material with high-intensity on T2.
Case Discussion
This case demonstrated a periapical abscess associated with acute sinusitis as an incidental finding in a patient being evaluated for other reasons.
Dental abscesses can exert pressure on the root of tooth, which contains the neurovascular bundle, and can lead to devitalisation of the tooth.
