Primary Hyperparathyroidism MCQ - Free Question
Q) Which is not a feature of primary hyperparathyroidism?
a) Increase Parathormone
b) Increase Calcium
c) Decreased phosphate
d) Dystrophic calcification
Answer – Free

Answer: d) Dystrophic calcification

Explanation: Clinical features of primary hyperparathyroidism include subperiosteal bone resorption, increased serum calcium, decreased phosphate levels, and elevated PTH. Dystrophic calcification is not typically seen in this condition.

Primary hyperparathyroidism is most commonly caused by parathyroid adenoma (75%) and can be localized using sestamibi scan. Kidney stones are the most frequent symptomatic manifestation. It is defined by hypercalcemia with inappropriately normal or elevated PTH.

Associated disorders: peptic ulcers, pancreatitis, bone disease, and CNS symptoms.

Indications for surgery in asymptomatic patients include:

  • Age < 50 years
  • High urinary calcium excretion
  • Low creatinine clearance
  • Kidney stones
  • Very high serum calcium
