Abstract Thyroid storm due to gestational trophoblastic disease (GTD) with metastatic choriocarcinoma is a rare but potentially life-threatening endocrine emergency. We report on a woman with molar pregnancy and metastatic choriocarcinoma who presented with thyroid storm (Burch-Wartofsky point scale of 45) a few weeks after the evacuation of GTD. She was initially managed with intravenous hydrocortisone, oral propylthiouracil (PTU), and esmolol infusion. After stabilization in the intensive care unit, 10 cycles of chemotherapy with etoposide, methotrexate, leucovorin, dactinomycin, and cyclophosphamide (EMA-CO) were initiated for stage 4 choriocarcinoma with brain and lung metastases. She underwent a hysterectomy soon after completing chemotherapy and received an additional 3 cycles of chemotherapy after the hysterectomy. As human chorionic gonadotropin (hCG) levels normalized, thyroid function reverted to normal as well. At the last follow-up, the patient was asymptomatic, euthyroid (without antithyroid medication), had a normal hCG titer of 1.7 mIU/mL (normal nonpregnant reference is 5 mIU/mL), and the lung and brain lesions had resolved entirely. Management of thyroid storm in the presence of untreated metastatic choriocarcinoma requires a high index of suspicion and a multidisciplinary team approach to prevent complications and improve survival.
