A Diagnosis Not to Miss!

Abstract

A 25-year-old previously healthy male patient, who was a smoker, presented with a one-week history of cough. He experienced a sudden onset of left-sided chest pain while coughing on the day of presentation. He denied fever, sputum production, recent trauma, or family history of lung disease. He had mild shortness of breath. His exam revealed a thin, tall patient with mild distress. Vital signs were stable. Oxygen saturation was normal. His neck exam showed no abnormalities. The chest exam showed decreased air entry on the left side and hyperresonance to percussion with no local tenderness.
