A 65-year-old woman (breast cancer 2 years ago) has bone loss in all upper-left quadrants and a multilocular, soap-bubble radiolucent lesion between #2 and #3. Most likely diagnosis?
Show answer and explanation
Correct answer: C. Ameloblastoma
- A. Incorrect – usually a unilocular radiolucency scalloping between roots, not multilocular soap-bubble.
- B. Incorrect – the breast-cancer history is a distractor; metastases are usually ill-defined/ragged, not soap-bubble multilocular.
- C. Correct – a multilocular 'soap-bubble' radiolucency is the classic radiographic hallmark of ameloblastoma.
- D. Incorrect – OKCs are typically well-defined and grow antero-posteriorly without expanding; not classic soap-bubble.
