Discussion of Ameloblastoma
- Ameloblastomas are benign epithelial neoplasms
- Represent about 10% of odontogenic tumors.
- Exhibit locally aggressive behavior.
- Typically manifest in the 3rd to 5th decades of life.
- Patients usually present with a slow-growing, painless mass.
- Most ameloblastomas occur in the ramus and posterior body of the mandible (80% of cases).
- Treatment of ameloblastoma depends on the extent of tumor infiltration through the cyst wall and into surrounding bone.
- Excision of a relatively contained ameloblastoma could involve localized removal of the lesion with wide margins
- If the lesion is highly infiltrative and extensive, en bloc resection would be performed.
 Imaging Findings for Ameloblastoma
- Ameloblastomas can vary in their radiographic appearance.
- Some appear as well-defined, unilocular, well-corticated, lucent lesions that are often associated with the crowns of impacted or unerupted teeth; as a result, such ameloblastomas are indistinguishable from odontogenic keratocysts and dentigerous cysts at radiography.
- Other ameloblastomas are multilocular with internal septa and a honeycomb or soap bubble appearance and are often similar in appearance to large odontogenic keratocysts.
- Ameloblastomas are typically expansile with an osseous shell that represents the involved bone.
- CT findings include cystic areas of low attenuation with isoattenuating solid regions.
