Pulmonary haemorrhage can be life threatening and can be associated with high mortality
Clinical presentation may mimic multiple pathologies.
Initial aetiology may not be clear and treatment for potential underlying causes with resuscitation should be initiated early
CT thorax angiogram is the initial investigation of choice and can guide diagnosis, differentiate between diffuse alevolar and focal haemorrhage and also guide embolisation if appropriate.
