Chance finding on a 42-year-old man of a well-defined unilocular lucency 8 x 9 mm in the incisive canal. The normal maximum diameter of the canal is 6 mm.
The patient should be referred to an oral surgeon for surgical evaluation as these cysts can grow to a large size.
In addition, there is mucosal thickening of the left maxillary sinus floor probably due to sinusitis.
