Hobnail papillary thyroid carcinoma (HPTC) is a moderately differentiated PTC variant with aggressive clinical behavior and significant mortality.The purpose of this study was to recognize the unique MRI features of HPTC .61 patients with PTC confirmed histopathologically[19 lesions of HPTC and 42 NHPTC (PTC without hobnail features)lesions] undergoing MRI with T1W, T2W,DWI and contrast material–enhanced sequences prior to thyroidectomy were included retrospectively. there was a significant tendency toward T2WI significantly high signal 、T2WI linear low signal 、Lace levy 、Gyrus-like structure 、higher ADC values 、irregular shape present in HPTCs. HPTC lesions have unique MRI features.
