Introduction: Thyroid storm is a rare but life-threatening endocrine emergency. It is an acute exaggerated clinical manifestation of thyrotoxic state. We report an impending thyroid storm caused by a hydatidiform mole in a 14-year-old girl. This paper intends to describe hyperthyroidism secondary to molar pregnancy highlighting the rare but essential evaluation of hyperthyroidism.

Case: A 14-year-old girl was consulted by the obstetric division to evaluate and manage hydatidiform mole with suspected hyperthyroidism. She had frequent palpitations and tremors for 1 week ago. She also complained of nausea and vomiting 1 week before admission to the hospital. We found a Burch-Wartofsky score of 25, which was categorized as an impending thyroid storm. Laboratory results showed mild anemia, low thyroid stimulating hormone (TSH) levels, high free thyroxine (T4) levels, and markedly elevated beta-human chorionic gonadotropin (beta-hCG) levels, normal Thyroid-stimulating hormone receptor antibodies (TRAb). Other laboratory parameters are mediocre. The ECG results showed sinus tachycardia. A mole tissue biopsy of the uterus confirms the morphology of the hydatidiform mole. These findings established the diagnosis of Impending Thyroid Storm caused by a hydatidiform mole.

Conclusion: A hydatidiform mole can cause thyroid storm because the hormone hCG has similar structure to TSH. Doctors should always estimate the possibility of hyperthyroidism in a molar pregnancy.
