        failure of Thyroid Migration during development
        
        Clinical Case
        
        Notes:
        
        note that the thyroid gland actually migrates down to below he cricothyroid cartilage joint
        
        failure of this migration results in ectopic thyroid
        --> this can be sublingual, etc.
