Unerupted carious RL8 tooth with periapical lucency extending into the inferior alveolar canal, with erosions of both the buccal and lingual cortices of the mandible. Sclerosis and periosteal reaction of the mandibular ramus. There is also a small cortical defect in the right mandibular condyle.
Immediately overlying the buccal cortex defect there is a submasseteric abscess, spreading through the masticator space. The right masseter is enlarged and there is retromaxiallary stranding, with reactive platysmal thickening inferiorly, but no deep neck space collection. No parotid collection.
Known incidental right submandibular calculus between mylohyoid and hyoglossus, but no duct dilatation nor submandibular gland enlargement.
No left sided abnormality.
With dental infections it is important to examine the masticator space for any submasseteric collections which can be clinically hidden.
