Fig. 3

Male patient aged 65 years presented with left lobe nodule. Ultrasound features of the nodule A: The left lobe shows solid nodule isoechoic to the surrounding thyroid tissue, wider more than taller with well-defined outline. Marginal macro-calcifications are noted. TIRADS categorization: TIRADS (5). On elastography color map B: most of the nodule is shaded with blue with small green areas are seen. Elastography score: (3) Strain ratio = 8.7. MRI study: T2 weighted image C: left lobe nodule isointense to the surrounding normal thyroid parenchyma. Diffusion weighted images D: the nodule shows high signal intensity. ADC mapping E: it shows low signal with ADC value = 0.68 × 10−3. Pathology: papillary thyroid carcinoma
