Abstract

Intravenous mercury poisoning is a rare but severe medical emergency, often resulting from accidental exposure or intentional self-harm. We present the case of a 30-year-old male with a history of sickle cell anemia who presented with high-grade fever, vomiting, giddiness, and breathlessness following intravenous mercury self-administration. Diagnostic challenges included distinguishing symptoms of acute mercury toxicity from those of his chronic condition of sickle cell trait. Markedly elevated serum mercury levels confirmed the diagnosis, with high-resolution computed tomography (HRCT) imaging studies revealing mercury deposits and alveolar lung injury. Management involved antidote of mercury poisoning, including non-invasive ventilation and transfusions, with consultations from multiple specialties. The patient demonstrated significant clinical improvement and was discharged with scheduled follow-ups. This case underscores the complexity of diagnosing and managing intravenous mercury poisoning, highlighting the importance of a comprehensive multidisciplinary approach for optimal patient outcomes.
