Know the underlying causes of coughing up blood!

Hemoptysis is when a patient coughs up blood or blood sputum from bronchi, larynx trachea or lungs. The most common underlying causes that can be detected with CT are:

  • Tuberculosis
  • Bronchiectasis
  • Chronic Bronchitis
  • Pneumonia
  • Fungal infections
  • Lung malignancy

*Massive Hemoptysis is the bleeding more than 300ml within 24 hours.

How is Hemoptysis evaluated?

The imaging modalities that are pertinent to the evaluation of hemoptysis are:

  • Chest Radiograph– It lateralize the bleeding with a higher degree of certainty and can often help in detecting underlying parenchymal and pleural abnormalities.
  • MDCT– Contrast-enhanced MDCT is capable of demonstrating the site of bleeding. It provides high-resolution angiographic studies of thoracic and upper abdominal vasculature that are useful prior to anticipated bronchial artery embolization or surgical intervention.
  • Thoracic aortography (Bronchial artery embolization)– It is the most effective therapy for controlling massive hemoptysis. In more than 90% of hemoptysis cases requiring intervention with arterial embolization or surgery, the bronchial arteries are responsible for bleeding.
