Which imaging finding is most commonly associated with hyperparathyroidism?

• A. Salt and Pepper Skull
• B. Hyperparathyroidism
• C. Paget's disease
• D. Osteoporosis

Answer: (A)

The main concept is that hyperparathyroidism produces distinctive bone changes from increased osteoclastic activity, especially in the skull. In longstanding disease, diffuse resorption of the trabeculae in the calvarium creates a granular, punctate pattern known as the salt-and-pepper skull. This radiographic appearance is a classic, pretty specific sign of hyperparathyroidism, making it the best choice. Other options don’t fit as well. Paget’s disease of bone has a different skull appearance, often with thickened, coarsened trabeculae and a cotton-wool look. General osteoporosis is a nonspecific finding of reduced bone density and doesn’t produce the characteristic granular skull pattern. The term “hyperparathyroidism” itself isn’t an imaging finding, but the salt-and-pepper skull is a classic radiographic manifestation you’d look for in this condition.
