Systemic versus Pulmonary Bleeding in Lung Infection: Value of CT in Two Cases

Abstract

Bronchial and pulmonary artery aneurysms are rare causes of hemoptysis in the course of lung infection, for which early diagnosis and treatment are essential to prevent fatal bleeding. Depending on patient condition, these occurrences are amenable to computed tomography (CT) to determine both the cause of hemoptysis and the bleeding site in order to plan the most effective bleeding-control procedure. In this report, we illustrate the importance of the bleeding site identification using CT in two cases of infection-related hemoptysis.
