INTRODUCTION: Many patients presenting to urban emergency departments (EDs) have chief complaints directly related to the use of illicit drugs. Given the reluctance of patients to admit to their use of cocaine, it is important for the emergency medicine provider (EMP) to recognize key epidemiologic principles as well as features of the history, physical examination, and diagnostic studies that suggest the sequelae of cocaine abuse. CASE PRESENTATION: We describe our assessment of an otherwise healthy 47-year-old man with the acute onset of pleuritic chest pain accompanied by hypoxia, radiographic evidence of diffuse alveolar hemorrhage (DAH), and an elevated creatine phosphokinase (CPK) level. The patient vehemently denied active cocaine abuse. No clear pulmonary, cardiac, or infectious explanations for his signs and symptoms were readily apparent. Ultimately, after further workup and urine toxicology screening, the cause of this patient's chest pain and hypoxia was determined to be DAH related to his recent inhalation of crack cocaine. The patient was treated with systemic corticosteroids and improved. CONCLUSION: Nearly 41% of patients who present to the ED because of complications of inhaled cocaine use are experiencing pleuritic chest pain, and more than half have an elevated CPK concentration. As many as 40% of these patients deny using the drug when asked. These data are important for EMPs to know when formulating a differential diagnosis for patients presenting with pleuritic chest discomfort.
