A patient presents with B/L proptosis, heat intolerance and palpitations; most likely diagnosis here would be:
Hashimoto's thyroiditis
Thyroid adenoma
Diffuse thyroid goitre
Reidel's thyroiditis
In the above scenario, the patient exhibit the symptoms of hypehyroidism. Only diffuse thyroid goitre shows hypehyroidism here, all others are state of hypothyroidism. Ref: In a Page Surgery By Scott Kahan, John J. Raves, 2003, Page 99.
