Question

Pseudofractures are seen in

• A. Osteomalacia
• B. Multiple myeloma
• C. Osteoporosis
• D. Skeletal metastasis

Hint:

Think about which bone disease involves a mineralization defect rather than just bone loss.

Answer 1

The Correct Option is A

This question checks whether you can link a named radiological sign to the specific bone disease that produces it.

1. Osteomalacia: correct, unmineralized osteoid along stress lines gives the classic Looser's zone or pseudofracture appearance.
2. Multiple myeloma: wrong, it causes discrete punched-out lytic lesions from clonal plasma cell deposits, a different radiological picture.
3. Osteoporosis: wrong, bone density is reduced but mineralization stays normal, so no pseudofractures form.
4. Skeletal metastasis: wrong, metastatic deposits give lytic or sclerotic lesions, not linear unmineralized bands.

Correct answer: Osteomalacia.
