Overview

Head and neck MRI may be helpful in the diagnosis of ameloblastoma. Findings on MRI diagnostic of ameloblastoma include mixed solid and cystic pattern, thick irregular walls with papillary solid structures projecting into the lesion.

MRI

Head and neck MRI may be helpful in the diagnosis of ameloblastoma. Findings on MRI diagnostic of ameloblastoma include:

• Enhancement in the solid portion of the tumor.
• No enhancement in the cystic portion.
• Detection of thick walls in ameloblastomas lesions.
• Round area of radiolucency if it is unicystic.
• Thick rim-enhancement is seen.
• Enhancement of small intraluminal nodules.
