Intracranial primary malignant melanoma remains a complex radiological diagnosis that relies on the exclusion of other potentially more common entities and an optimal multidisciplinary approach.BACKGROUND Myxedema coma is an endocrine emergency with a high mortality rate, defined as a severe hypothyroidism leading to hypotension, bradycardia, decreased mental status, hyponatremia, hypoglycemia, and cardiogenic shock. Although hypothyroidism and cardiac disease has been interlinked, ST elevation myocardial infarction in the setting of myxedema coma have not been reported previously. CASE REPORT We report the case of a 70-year-old man who presented to the Emergency Department with chest pain and confusion. He also reported fatigue for the past week, which was progressively worsening. His past medical history was significant for renal cell carcinoma with metastatic bone disease being treated with chemotherapy (axitinib and pembrolizumab). In the Emergency Department, an ECG revealed inferior ST elevations. Shortly after presentation, the patient's blood pressure was decreasing, he became bradycardic (sinus), and his mental status was getting worse, so he was intubated for airway protection and was taken emergently for a cardiac catheterization, which failed to reveal an acute coronary occlusion. TSH was 60.6 mIU/L (0.465-4.680) mIU/ML, and free T4 0.3 ng/dL (0.8-2.2) ng/dL. The cardiac index was calculated to be 0.8 L/min/m² (normal range 2.6-4.2 L/min/m²), which confirmed cardiogenic shock due to myxedema coma. He was treated with levothyroxine (T4), liothyronine (T3), hydrocortisone, and multiple vasopressors but failed to respond and died 13 h after admission to the hospital. CONCLUSIONS Because of its rarity and high mortalit
