A patient presents with sudden pleuritic chest pain, shortness of breath, and a nonproductive cough. Which condition is most likely?

• A. Pulmonary Embolism
• B. Aortic Dissection
• C. Pneumothorax
• D. Myocardial Infarction

Answer: (A)

Pleuritic chest pain with sudden onset and shortness of breath strongly points to a pulmonary issue involving the lung surface. A pulmonary embolism fits best because a clot traveling to the lungs abruptly obstructs part of the pulmonary circulation, causing rapid breathing and pleuritic pain that worsens with inhalation. A dry (nonproductive) cough can accompany this as the pleura becomes irritated by the clot and the associated inflammation. While other conditions can cause chest pain and shortness of breath, their typical clues aren’t as consistent with this presentation. Aortic dissection usually presents with a severe tearing pain that may radiate to the back and can involve pulse or blood pressure differences. Pneumothorax can cause sudden pleuritic pain and shortness of breath as well, but often features decreased or absent breath sounds and hyperresonance on the affected side. Myocardial infarction tends to produce pressure-like chest pain rather than pleuritic pain, and a nonproductive cough isn’t a characteristic feature. So the combination of sudden pleuritic pain, shortness of breath, and a dry cough most strongly indicates a pulmonary embolism.
