What is Peribronchovascular Distribution on CT imaging?

A common finding described on computed tomography (CT) imaging. A disease with a peribronchovascular distribution involves the bronchi, adjacent lymphatics, and associated vasculature surrounding the central or axial lung interstitium.

• Pulmonary Lymphoma
• Organizing Pneumonia
• Eosinophilic Pneumonia
• Sarcoidosis
• Infection
• Vasculitis
• Pulmonary Hemorrhage
