Case of the Month: March 2024
Clinical history
A 35-year-old female patient has an asymptomatic thyroid mass that was diagnosed 6 years ago as a 10 mm “cyst” that was followed by surveillance. It recently became larger in size, to “almost double the size”, and prompted the patient to seek medical care. Thyroid hormone and TSH levels were within normal limits, and there was no cervical lymphadenopathy. The physical examination revealed a palpable neck mass on the left side of the neck, but was otherwise unremarkable. Ultrasound showed a left 2.0 x 1.7 cm mass, TIRADS 4. The patient underwent a fine needle aspiration of the thyroid mass.
