Thyroid Uptake Scans
(Technetium 99)
(A) Normal
(B) Graves disease: diffuse increased uptake in both thyroid lobes.
(C) Toxic multinodular goiter (TMNG): “hot” and “cold” areas of uneven uptake.
(D) Toxic adenoma: increased uptake in a single nodule with suppression of the surrounding thyroid.
(E) Thyroiditis: decreased or absent uptake.
Maternal Graves Disease - "The dose of anti-thyroid drug usually needs to be decreased during pregnancy, and often Graves disease remits completely and the medication can be withdrawn. This is probably due to the overall immunosuppressive effect of pregnancy."
Graves' disease in mothers can cause thyrotoxic fetus - may have increased fetal motility and develop a range of abnormalities including: goitre, tachycardia, heart failure associated hydrops, growth retardation, craniosynostosis and accelerated bone maturation.
