Radiology · Musculoskeletal imaging: acromegaly of the hand
Sample itemA man with enlarging hands and jaw has a hand radiograph showing broad spade-like terminal phalangeal tufts, widened joint spaces and thickened soft tissues. Which condition is most likely?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Acromegaly
Acromegaly causes spade-like tufts, widened joint spaces from cartilage overgrowth, and thickened heel pad and soft tissues. Resorption of the tufts is instead seen in systemic sclerosis and hyperparathyroidism.
Option by option
A. Acromegaly (correct)
Correct. Spade-like tufts and widened joint spaces with soft-tissue thickening indicate acromegaly.
B. Hyperparathyroidism
Hyperparathyroidism causes subperiosteal and tuft resorption rather than overgrowth.
C. Hypothyroidism
Hypothyroidism causes delayed bone age and epiphyseal dysgenesis.
D. Systemic sclerosis
Systemic sclerosis causes tuft resorption and soft-tissue calcification.
