  • Figure 1
    US findings
     

    Axial scan in the midline: The left lobe of the thyroid gland is missing. NOTE: small colloid cyst is on the right side.

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Axial scan of the right neck: Right lobe anteroposterior and laterolateral diameters are 2.11 cm and 2.46 cm, respectively.

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Longitudinal scan of the right thyroid lobe: Note that a nodus and a colloid cyst are present in the posterior part.

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Axial scan of the isthmus containing a nodus and a small cyst.

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 2
    MRI findings
     

    MRI axial T1W image: The left thyroid lobe is missing. NOTE: slight anterior neck asymmetry

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Coronal T1W image. Absent left thyroid lobe. Note the slight deviation of the trachea to the left.

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Congenital;

    MRI axial T2W image showing the same findings as figure 2a.

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Coronal T2W image showing the same findings as figure 2b.

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 3
    Nuclear scintigraphy study

    Nuclear scintigraphy coronal projection of the neck: There is no nuclear uptake in the left thyroid lobe.

     
    Area of Interest: Thyroid / Parathyroids; Imaging Technique: Nuclear medicine conventional; Procedure: Diagnostic procedure; Special Focus: Congenital;
