Which of the following is consistent with diagnosis of De-Quervain thyroiditis?
High-Yield Explanation
De Quervain thyroiditis is characterised by fever, constitutional symptoms and painful enlarged thyroid due to viral etiology. Initially T4 and T3 are elevated due to damage to follicles. RAIU uptake is reduced. Subsequently hypothyroid phase sets in and RAIU becomes normal. Option A is wrong due to increased RAIU uptake which is never possible in viral thyroiditis. Option B is consistent with Grave's disease with increased RAIU. Option C indicates Central hypothyroidism. Option D indicates late phase of De Quervain thyroiditis.
