|Prompt=A 45-year-old female comes to the physician due to a 6-month history of difficulty swallowing. She is very worried because her condition is getting worse. At first, she thought it was a cold. Review of systems is significant for dyspnea and stridor. Upon examination her vitals are within normal limits, her neck is supple without JVD and her thyroid has a hard consistency and non-mobile. Her TSH and free T3 and T4 are within normal limits. A fine needle aspiration is performed on it shows dense collagenous replacement of the thyroid gland with chronic inflammation. Which of the following complications is this patient most likely to develop? | |Prompt=A 45-year-old female comes to the physician due to a 6-month history of difficulty swallowing.
