Pulmonary haemorrhage in children is a non-specific response to a number of varying insults. Many of these insults favour particular anatomic foci along the pulmonary and bronchial arterial trees respectively. Although recent years have seen an emerging interest in the understanding and classification of pulmonary vasculitides, this pathophysiology represents only one subset of the causes of pulmonary haemorrhage in children. Our purpose is to review the imaging and pathophysiologic manifestations of varying causes of pulmonary haemorrhage according to the anatomic region of susceptibilities in the pulmonary arterial and bronchial artery trees.

We aim to provide a perspective of imaging manifestations of the pathophysiologies of pulmonary haemorrhage displayed schematically according to their relative anatomic areas of susceptibility. We aim to focus on useful constellations or associated findings that will serve to help the reader differentiate amongst entities that often have otherwise similar imaging presentation. Read More

The anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of autoimmune diseases characterized by vascular inflammation requiring immunosuppressive treatment. Involvement is most common of the kidneys and lungs, although there is a paucity of literature reporting the chest imaging findings in children. Our goal is to describe the salient chest imaging findings of pediatric AAV to promote recognition by radiologists. Read More

Takayasu's arteritis (TA) is one of the most common childhood vasculitides, primarily involving large and, to a lesser extent, medium sized arteries. The aorta and pulmonary arteries are most frequently affected. Historically, diagnosis depended on typical fluoroscopic angiographic features, in conjunction with a number of clinical and hematologic criteria. Increasingly, a range of imaging modalities is used in initial diagnosis as well as for monitoring disease progression and treatment response. The purpose of this educational exhibit is to provide an update on the current role of imaging in TA, defining disease extent and activity, as well as highlighting end organ complications. Read More
