title: Ultrasonographic findings of thyroid in patients with Hashimoto thyroiditis: overt hypothyroid and euthyroid.
abstract: OBJECTIVE
  To compare the frequency, size, and sonographic features of thyroid nodules in overt hypothyroid and euthyroid patients with Hashimoto thyroiditis.
  
  
  METHODS
  The study included 135 overt hypothyroid (group 1) and 74 euthyroid patients (group 2) with Hashimoto thyroiditis. The two groups were compared for presence of nodule(s), nodule numbers, and nodule sizes obtained by ultrasonography.
  
  
  RESULTS
  Nodules were found in 48 (35.5%) patients in group 1 and in 24 (36.9%) in group 2 (p more than 0.05). The numbers of nodules in the group 1 and group 2, respectively, were as follows: single nodule in 12 (25%) and in 9 (33.3%) patients; 2-4 nodules in 20 (41.6%) and in 13 (48.1%) patients; and > 4 nodules in 16 (33.3%) and in 5 (18.5%) patients (p more than 0.05 for all of the results). Nodule sizes of the solitary or dominant nodule in group 1 and group 2, respectively, were as follows: less than 1 cm nodules in 27 (56.2%) and in 14 (51.8%) patients; 1-2 cm nodules in 18 (37.5%) and in 7 (25.9) patients; 2-4 cm nodules in 2 (4.1%) and in 5 (18.5%) patients and > 4 cm nodules in 1 (2%) and in 1 (3.7%) patient (p more than 0.05 for all of the results).
  
  
  CONCLUSIONS
  Thyroid ultrasound examination of overt hypothyroid and euthyroid patients with Hashimoto thyroiditis reveals similarities in terms of frequency, number, size, and ultrasound features of the thyroid nodules.
