The scintigraphic findings in @entity2621 are highly variable and can mimic any @entity1374 . In this study, we compared the scintigraphic findings with ultrasonography in 48 @entity1 with @entity2621 . Thyroid scintigrams revealed @entity1373 in 12 @entity1 , @entity1376 in 20 @entity1 and a solitary nodule in 16 @entity1 (toxic @entity652 , n = 1; hypoactive nodule, n = 4; hyperactive nodule with no suppression, n = 3; normoactive nodule, n = 8). Ultrasonography revealed @entity1373 in 19 @entity1 , @entity1376 in 20 @entity1 and a solitary nodule in 9 @entity1 . The thyroid scan and ultrasonography revealed the same findings of @entity1373 in 12 @entity1 and @entity1376 in 20 @entity1 . Of the 16 @entity1 with a solitary nodule on scintigraphy, only 9 showed the same finding on ultrasonography, with the other 7 showing @entity1373 . The difference in nodularity between thyroid scanning (74.9%) and sonography (60.4%) has been attributed to pseudonodularity in @entity2621 . In conclusion, our results confirmed that @entity2621 can mimic any @entity1374 , including @entity1373 , @entity8170 and @entity1376 on scintigraphy. Therefore, scintigraphy, ultrasonography and serum thyroid hormone estimation alone may not be helpful for the final diagnosis of @entity2621 . To eliminate unnecessary surgical intervention, all @entity1 should be evaluated by means of physical examination and thyroid autoantibodies, in addition to a thyroid scan, ultrasonography, serum thyroid hormones and fine-needle aspiration biopsy when necessary.
