Abstract

Background: Graves’ disease is the most common cause of hyperthyroidism, but its initial presentation in the emergency department (ED) may often be subtle or masked by concurrent acute illness. Influenza A associated pneumonitis is also a serious infectious condition that can present with high-grade fever, cough, and hypoxemia. The co-occurrence of these two entities is rare, and incidental detection of Graves’ disease in such a setting is clinically significant. Case Presentation: We report the case of a 24-year-old male who presented to the DAOH Emergency Department with acute onset high-grade fever, cough, throat pain, and reduced oral intake. On arrival, he was febrile, tachycardic (160/min), and severely dehydrated. Initial evaluation suggested left lower lobe neumonitis, later confirmed as Influenza A (H3)-associated by respiratory viral panel. Despite adequate hydration and antipyretic therapy, persistent sinus tachycardia prompted further workup. Thyroid function tests revealed suppressed TSH with elevated T3 and T4, and thyroid ultrasound demonstrated diffuse enlargement with pervascularity, consistent with Graves’ disease. The diagnosis was confirmed with elevated TSH-receptor ntibodies. The patient was managed with supportive care, oseltamivir for influenza, antibiotics for pneumonitis, nd initiated on neomercazole with beta-blockade for hyperthyroidism. He improved clinically and was ischarged in stable condition on day
