Lesions vc. nodule - case 252
Clinical data: A 27-year-old woman was referred for evaluation of growing nodules. She was treated for hypothyroidism for 19 years. On the first ultrasound multiple echonormal and hyperechogenic nodules were described and the largest one was aspirated. The cytological diagnosis was suspicion of follicular carcinoma. A subtotal left lobectomy was performed when she was 10. Histopathology disclosed Hashimoto's thyroiditis without any nodules. On regular follow up the hyperechogenic nodules were found to increase in size, from 8 to 11 and from 12 to 16 mm over fifteen years.
Palpation: Both lobes were firm. No nodules could be palpated.
Laboratory data: euthyroidism on daily 162.5 microgram levothyroxine (TSH 0.92 mIU/L).
