Dental abscess and maxillary sinusitis

Case contributed by Dr Bruno Di Muzio

Presentation

Incidental finding.

Patient Data

Age: 20
Gender: Male
CT

CT Brain Angiogram (selected images)

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

MRI Brain (selected images)

MRI Brain performed for other reasons shows signs of acute sinusitis within the right maxillary sinus characterised 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.
