Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.


CT through the maxilla obtained with contrast demonstrates a cystic lesion displacing the roots of the second incisor and canine on the left. The bone is thinned and expanded. Posteroinferiorly an enhancing mural nodule is noted.

Case Discussion

This appearance is typical of an ameloblastoma despite the atypical location. This was histologically confirmed.


Unicystic ameloblastoma: mural variant (poorer prognosis than unicystic luminal variant, but better than multicystic ameloblastoma).
