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.
