Imaging findings with Oncologically Relevant Findings Reporting and Data System category 4 in neck region. Axial T2-weighted (A) and contrast-enhanced T1-weighted (B) images show solid thyroid nodule (arrows) in right lobe of 63-year-old woman. Corresponding color Doppler ultrasound image (C) reveals 1.3-cm hypoechoic and hypervascular lesion with histopathology diagnosis of papillary carcinoma. In 67-year-old man, solid lesion (arrowheads) with adjacent daughter nodule was detected in right parotid gland, demonstrating hyperintensity on T2-weighted image (D) and contrast enhancement on T1-weighted image (E). Lesion was hypoechoic on ultrasound image (F) and was determined to be Warthin’s tumor by fine-needle aspiration cytology
