Area of Science:

• Cardiology
• Radiology
• Pulmonology

Background:

• Exertional dyspnea is a common symptom that can indicate underlying cardiopulmonary disease.
• Pulmonary embolism (PE) is a potentially life-threatening condition caused by a blockage in the pulmonary arteries.
• Early diagnosis and treatment of PE are crucial for patient outcomes.

Observation:

• A 55-year-old male presented with exertional dyspnea.
• Chest X-ray demonstrated the Westermark sign, suggestive of reduced pulmonary blood flow.
• Computed tomography (CT) scan revealed a Hampton hump, a wedge-shaped opacity indicating pulmonary infarction.

Findings:

• The diagnostic imaging findings were consistent with bilateral pulmonary embolisms.
• The Westermark sign and Hampton hump are classic radiological indicators of PE.

Implications:

• This case highlights the importance of recognizing specific radiological signs for prompt PE diagnosis.
• Accurate and timely diagnosis of bilateral pulmonary embolisms can significantly improve patient prognosis.
• Further research into the early detection of PE in patients with exertional dyspnea is warranted.
