Sudden respiratory distress in an elderly male revealed pulmonary embolism, presenting as asthma unresponsive to treatment. This case highlights a critical diagnostic challenge, emphasizing the need to consider pulmonary embolism in such scenarios.

Area of Science:

  • Pulmonology
  • Cardiology
  • Emergency Medicine

Background:

  • Pulmonary embolism (PE) is a significant cause of acute respiratory distress.
  • Asthma-like symptoms can sometimes mask underlying PE.

Observation:

  • An 82-year-old male without prior respiratory disease presented with acute respiratory distress and bilateral sibilant rales.
  • Initial presentation mimicked acute asthma refractory to bronchodilator therapy.

Findings:

  • Angiography confirmed moderately severe pulmonary embolism as the cause of respiratory distress.
  • Bronchospasm in acute PE may result from alveolar hypocapnia and platelet mediators via a vagal reflex.

Implications:

  • Clinicians must consider pulmonary embolism in patients with unexplained bronchospasm, especially when bronchodilators are ineffective.
