abstract: The causes of hemoptysis are various, often the patient’s history and physical examination can narrow potential differential diagnosis, and even pseudohemoptysis with a source of bleeding located outside the lungs is possible. A chest radiograph is needed and can identify the cause in up to one third of the cases.
