Pattern Recognition: Uncommon Clinical Scenarios
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.

The normal thymus in small children and adolescents will appear to have hyperechoic foci that mimic microcalcifications, seen on the right side of the video clip frame (between the strap muscles and carotid artery) (MP4 2175 kb)
