Ameloblastoma is classically seen as a multiloculated (80%), expansive "soap-bubble" lesion, with well-demarcated borders and no matrix calcification.
On MRI, ameloblastomas demonstrate a mixed solid and cystic pattern, with a thick irregular wall, often with solid papillary structures projecting into the lesion.
AmeloblastomasÂ are benign, locally aggressive tumors that arise from the mandible, or less commonly from theÂ maxilla.
Ameloblastomas are the second most common odontogenic tumor (odontomaÂ is the most common) and account for up to one-third of such cases.
Ameloblastomas typically occur as hard painless lesions near the angle of the mandible in the region of the 3rdÂ molar tooth.
Unsurprisingly, ameloblastomas arise from ameloblasts, which are part of the odontogenic epithelium, responsible for enamel production and eventual crown formation.
