title: Riedel thyroiditis: US, CT, and MR evaluation.
abstract: We report the ultrasound, CT, and MR findings in a patient with Riedel thyroiditis. The hypointensity of the lesion observed on T1- and T2-weighted sequences, especially when associated with infiltration of adjacent structures of the neck, can be suggestive of Riedel thyroiditis.
