Left floor of mouth swelling with concern for a ranula. The patient also has a history of perennial allergic rhinitis and the possibility of mild past vestibular neuritis. There is no evidence of a ranula or floor of mouth tumors. A right mylohyoid boutonierre deformity with minimal prolapse of the right sublingual gland is an anatomic variant. The submandibular and parotid glands appear unremarkable. There are mildly prominent upper cervical lymph nodes. For example, a left level 2 lymph node measures up to 15 mm in short axis. However, the lymph nodes display homogeneous signal characteristics. There is a left cerebellar hemisphere developmental venous anomaly. There is mild scattered paranasal sinus mucosal thickening and prominence of the nasal turbinate mucosa diffusely. There is torus mandibularis. The orbits and temporal bone regions bilaterally appear grossly unremarkable.
1. No evidence of ranula.2. Nonspecific mildly prominent upper cervical lymph nodes, which may be reactive.3. Mild scattered paranasal sinus mucosal thickening and prominence of the nasal turbinate mucosa diffusely are likely related to allergic rhinitis.
