Abstract
Objective
A conversion from Hashimoto's thyroiditis (HT) to Graves' disease (GD) and vice versa leads to diagnostic and therapeutic challenges.
Clinical Presentation and Intervention
A 30-year old woman presented with overt hyperthyroidism and negative thyroid-stimulating hormone receptor antibodies (TRAbs). Since hashitoxicosis was assumed, the patient was treated with propranolol. Within the next few weeks, the patient developed severe overt hypothyroidism, leading to treatment with levothyroxine. However, after several more weeks, the patient presented with overt hyperthyroidism once again, this time also showing elevated TRAbs.
Conclusion
We suggest educating patients and physicians to recognize changes in thyroid function and close monitoring of unclear cases of overt hyperthyroidism.<br>.
