Natural course of the disease. Table 6: the ultrasound pattern may be stable in Graves' disease - Case 6
First examination (TSH 0 U/mL, FT4 51.8 pM/L)
6 months later (TSH 1.17 mIU/L, FT4 17.2 pM/L)
10 months later (TSH 0 mIU/L, FT4 47.5 pM/L)

 

The basic pattern, i.e. the location and the shape of discrete hypoechogenic areas are unchanged irrespectively of the hormonal state. As in most cases of Graves' disease, the vascularization and the degree of hypoechogenicity are closely related to the thyroid function.
