Patient 5. Transversal (a) and longitudinal (b) scans of the hypoechogenic thyroid gland revealed the formation of the nodule 4 11/12 years since referral and 1 4/12 year since last ultrasound assessment. The growth of the nodule was fast from 6.5 × 5.5 × 3.2 mm to 6.6 × 9.8 × 4.1 mm in 8 months (132% increase). The nodule was surrounded by a hyperechogenic border. During follow-up, the echogenicity of the thyroid gland increased
