Graves or subacute thyroiditis ?

Both have symptoms of hyperthyroidism
Both have elevated T4 T3, Low TSH


However,
Radioactive iodine uptake, RAIU:
high in Graves, Low in subacute (De Quervain) thyroiditis

Thyroid palpation:
Tenderness in subacute thyroiditis
no tenderness in Graves

Opthalmopathy:
Only in Graves

ESR:
high in subacute thyroiditis


Mgt decision:
Subacute thyroiditis is transient (can occur post partum), only supportive care- Aspirin
Graves requires definitive tmt.
