Longitudinal grey scale ultrasound of the same case as in Figure  shows that in the subacute phase of de Quervain thyroiditis there is progression to involve almost the entire lobe (arrows).

Transverse power Doppler ultrasound shows a focal, ill‐defined, avascular, hypoechoic nodular area in the subcapsular region (arrow) in the acute phase of de Quervain thyroiditis.

⁶⁸Ga-DOTA peptide, staging of NET lung primary, comparison with FDG. Clinical history: 65 y.o. man. Staging of a lung mass with FDG PET and biopsy indicated a moderately differentiated NET (grade 2, Ki67 8%). Consequently, the patient underwent a second PET using ⁶⁸Ga-DOTANOC to stage the disease more accurately. PET/CT findings: increased focal uptake in FDG PET in the right lung, without any other findings (a MIP). ⁶⁸Ga-DOTANOC showed intense uptake in the lung and in the thyroid due to a known De Quervain thyroiditis (b MIP)

Classic morphology of subacute thyroiditis seen in our cases. (A) Multinucleated giant cell (Diff‐Quik, ×40). (B) Granuloma (Papanicolaou, ×40). (C) Scattered epithelioid histocytes, lymphocytic infiltrate, and a multinucleated giant cell (Papanicolaou, ×20).
