From: A comparative analysis of diffusion-weighted imaging and ultrasound in thyroid nodules
A 45-year-old man with papillary carcinoma of the left lobe of the thyroid (white arrow). a: axial T1WI showed low signal with multiple nodules in the left lobe, b: axial T2WI fat suppression on the same level showed high signal with unclear boundary, c: ADC map showed obvious high signal on the same level, and the ADC value is 1.0 × 10− 3 mm2/s, d: Ultrasound transverse section showed hypoechoic nodule in left thyroid lobe, irregular shape, unclear boundary, uneven echo, and multiple hyperechoic and hypoechoic points. TI-RADS:4c. e: HE staining (10*40) showed irregular and branching papillary in nodules, with packed arranged glassy cells with atypical nuclear, intranuclear inclusions and nuclear grooves were also observed, fibrous strips (pseudocapsule) were seen at the edge, and neoplastic cell nests infiltrated into the capsule
