QuestionSBA
QuestionChoice
This would suggest a diagnosis of Hashimoto's thyroiditis. This is also an autoimmune thyroid disease like Grave's disease, but this causes hypothyroidism, not hyperthyroidism.

e
TPO antibodies
QuestionChoice
This would most likely suggest post-partum thyroiditis. This is because the beta chain of hCG is very similar to the beta chain of TSH, therefore it can mimic TSH and activate the thyroid gland to produce fT3 and fT4. The typical clinical progression of post-partum thyroiditis is hyperthyroidism, followed by hypothyroidism, before returning to euthyroidism.

d
The discovery that the patient gave birth 3 months ago
QuestionChoice
This would most likely suggest a toxic adenoma due to there only being a single nodule on the thyroid gland. Even though there are signs of hyperthyroidism in the blood tests, the only way to confirm that this is Grave's disease is to look for the presence of TSH antibodies.

c
A single nodule on thyroid ultrasound
QuestionChoice
This would most likely indicate a toxic multinodular goitre. Even though there are signs of hyperthyroidism in the blood tests, the only way to confirm that this is Grave's disease is to look for the presence of TSH antibodies.

b
Multiple nodules during the neck examination
QuestionChoice
Grave's disease is an autoimmune condition in which there is an overproduction of antibodies that stimulate the TSH receptor. This causes an increase in fT3 and fT4, leading to symptoms of hyperthyroidism.

A 26-year-old male presents to the GP with tremors, visual disturbances, and constant sweating. The GP examines the patient and finds a swelling in the neck.

The GP performs blood tests that show: TSH <0.01 (low), fT3 - 16 (high), and fT4 - 41 (high).

What is the finding that will confirm that this is Grave's disease?
