Amyloid goiter mimicking subacute thyroiditis on clinical and imaging findings: A case report

Amyloid goiter (AG) is defined as the diffuse enlargement of the thyroid gland resulting from extensive amyloid deposition. Imaging findings in AG may vary depending on the amount of amyloid and fat deposition. A few case reports of AG with clinically subacute thyroiditis (SAT)-like syndrome have been published. However, there have been no reports on AG mimicking SAT with clinical and imaging findings. Herein, we present a case of AG mimicking SAT with a detailed report of the clinical and imaging findings.
