Pulmonary haemorrhage complicating multifocal infection is one of the causes of diffuse pulmonary haemorrhage (and particularly diffuse alveolar haemorrhage). The type of infection can depend on immunocompetency status as well as presence of absence of concurrent vasculitic, connective tissue or coagulative comorbidities.
Pathology
Causes
In immunocompromised patients, common considerations include 2
- cytomegalovirus pneumonia
- certain viral pneumonias
- invasive aspergillosis
- mycoplasma pneumonia
- legionella pneumonia
- pulmonary strongyloides infection
In immunocompetent patients, common considerations include 2
- certain viral pneumonias
- pulmonary manifestations of dengue fever
- pulmonary leptospirosis
