Solitary hyperfunctioning thyroid adenoma in a child. Elevated T3 and T4 levels with normal TSH level.

Surprising Findings
Elevated T3 and T4 levels occurred despite a normal TSH level.
Normally, high T3 and T4 suppress TSH. A normal TSH in the face of high thyroid hormones contradicts standard endocrine feedback logic and challenges diagnostic norms.
Practical Takeaways
Don’t rule out hyperthyroidism in children based solely on normal TSH levels if symptoms are present.

Sometimes, a harmless small tumor in a child's thyroid gland can make it overactive, leading to high levels of thyroid hormones — even when the main hormone that controls the thyroid looks normal in blood tests.
