"The most commonly described sonographic appearance is poorly defined regions of decreased echogenicity with decreased vascularity in the affected areas 1. These can be bilateral or unilateral. Sometimes the appearance is described as “lava flow,” with diffuse and confluent hypoechoic areas7. The thyroid gland size is mostly normal but can occasionally be enlarged or smaller in size 2."

"It is named after Fritz de Quervain (1868-1940), a Swiss surgeon."
"De Quervain thyroiditis is a clinical diagnosis based on history, laboratory results, and imaging findings 5,6. FNA is not routinely recommended 6."
"A viral infection (e.g. mumps, measles, coxsackie virus, adenovirus, Epstein-Barr virus, SARS-CoV-2 virus, influenza virus) typically precedes De Quervain thyroiditis 5,6. The viral antigen binds to HLA-B35 and activates cytotoxic T-cells, damaging thyroid follicular cells and releasing T3 and T4 thyroid hormones 5."
"elevated inflammatory markers, e.g. CRP, ESR (>50) 5,6"
"thyroid autoantibodies (e.g. anti-TPO, anti-thyroglobulin): may be high 5"
