Pattern Recognition: Uncommon Clinical Scenarios

  • Sathya Jyothinagaram

Patients presenting for evaluation of thyroid and parathyroid disease may not exhibit typical ultrasound patterns of their underlying diagnosis. These situations may pose challenges to the clinician because the ultrasound features may falsely mimic endocrine disease. This chapter demonstrates three scenarios where the ultrasound pattern is best interpreted in the overall context of the patient’s presentation.
