Benign Bone Lesions and Pathological Fracture – Board-Style Questions

What this deck covers

benign bone lesions and pathological fracture in 18 board-style clinical cases with worked explanations. Each case gives you a clinical vignette, four options, the correct answer, and an explanation of why each of the other three is wrong, with the guideline or textbook it follows named on the answer.

Board-style teaching questions for paediatricians and trainees preparing for paediatric board, MRCPCH and licensing examinations. Written from published guidelines and standard paediatric textbooks, with the source named on every answer.

The 18 cases, in order

1. A hollow at the top of the arm
2. A piece at the bottom
3. Bulging out of shape
4. Found by accident
5. A lump beside the knee
6. A lump that changes
7. Lumps in the family
8. The forearm that turns badly
9. When a quiet lesion is not quiet
10. After the netball catch
11. All down one side
12. A hazy shaft
13. Right at the end of the bone
14. The break comes first
15. When the hollow stays
16. A lesion that keeps growing
17. Will it break
18. A new swelling on an old lump

Diagnoses and management options tested

Across the 18 cases you are asked to choose between options such as: An area of infected bone that has softened and given way, The cavity holds fluid that the fragment sinks through, Solid cartilage arranged in rounded lobules throughout, Repeated films every three months until he stops growing, An outgrowth capped with cartilage, angled away from the joint, The position of the lump on the pelvis rather than on one of the limbs, A fault on the X chromosome passed through mothers, A short humerus with the elbow held bent, A gap in the outer wall with a swelling beside it, A pocket of infection that has eaten into the bone from within, A metabolic condition softening every bone in the body, A dense island sharply marked off from the marrow, Chondroblastoma, which arises in the growing end itself, Operate on the cavity now, while the arm is already painful.

Clinical pearls from this deck

• A break through a hollow upper humerus: a simple cyst.
• A fragment that sinks proves the cavity holds fluid.
• Levels inside a blown-out bone: blood-filled spaces.
• A wavy-edged cortical defect: leave it entirely alone.
• Marrow running into the lump: an osteochondroma.
• Growth after maturity with a thick cap: refer.

Work through the deck once for recognition, then again a week later to test yourself — each question gives the answer and explains why every other option fails.
