Figure 2:
A) Long-axis ultrasound image of the right thyroid lobe demonstrates a 1.5 x 1.0 x 1.3 cm hypoechoic wider than tall solid nodule with irregular margins and punctate echogenic foci (yellow arrow). Right thyroid lobe ultrasound in longitudinal (A, B) and transverse (C, D, E) planes demonstrate a 1.5 x 1.0 x 1.3 cm hypoechoic wider than tall solid nodule with irregular margins and punctate echogenic foci (yellow arrow). Mildly increased vascularity is exhibited on color Doppler investigation (B, D).
B) Transverse ultrasound image of the right thyroid lobe demonstrates a 1.5 x 1.0 x 1.3 cm hypoechoic wider than tall solid nodule with irregular margins and punctate echogenic foci (yellow arrow).
