What is interstitial fibrosis?
Interstitial lung disease is another term for pulmonary fibrosis, or “scarring” and “inflammation” of the interstitium (the tissue that surrounds the lung’s air sacs, blood vessels and airways). This scarring makes the lung tissue stiff, which can make breathing difficult.
Can interstitial fibrosis be cured?
The lung scarring that occurs in interstitial lung disease can’t be reversed, and treatment will not always be effective in stopping the ultimate progression of the disease. Some treatments may improve symptoms temporarily or slow the disease’s progress. Others help improve quality of life.
What is Peribronchovascular distribution?
Diseases that are predominantly peribronchovascular in distribution on computed tomography by definition involve the bronchi, adjacent vasculature, and associated lymphatics involving the central or axial lung interstitium.
How long can you live with fibrosis?
The average life expectancy of patients with pulmonary fibrosis is three to five years after diagnosis. However, early detection of the disease is key to slowing progression, and conditions such as chronic obstructive pulmonary disease (COPD) or pulmonary arterial hypertension (PAH) can impact disease prognosis.
What is a Peribronchovascular nodule?
Peribronchovascular nodules are seen adjacent to large bronchi and vessels in the central lung regions (Fig. 3.4A, green nodules). They can give the walls of bronchi and arteries a nodular appearance, or clusters of nodules may be seen.
What is Peribronchovascular thickening?
Peribronchovascular thickening is a broad imaging descriptive term commonly used to describe thickening of any one or more of the below: peribronchovascular interstitial thickening. bronchial wall thickening: can be differentiated from true peribronchovascular thickening on cross-sectional imaging.
Where is the peribronchovascular interstitium?
Thickening of the peribronchovascular interstitium, a connective tissue sheath that surrounds the central bronchi and pulmonary arteries. The peribronchovascular interstitium extends from the level of the pulmonary hila into the peripheral lung.
Which diseases are associated with the peribronchovascular interstitium?
Many of the diseases affecting the peribronchovascular interstitium are entities that show a predilection for lymphatic routes, such as sarcoidosis, pulmonary lymphangitic carcinomatosis, silicosis, and lymphoproliferative disorders.
How are fibrosing interstitial lung diseases (ILDs) monitored?
Close monitoring of patients with fibrosing interstitial lung diseases (ILDs) is important to enable prompt identification and management of progressive disease. Monitoring should involve regular assessment of physiology (including pulmonary function tests), symptoms, and, when appropriate, high-resolution computed tomography.
What is peribronchovascular disease?
Our discussion will concentrate upon peribronchovascular disease centered around and primarily affecting the axial interstitium. This involves diseases presenting as combinations of nodules, masses and/or focal ground-glass attenuation or air-space consolidation that have in common the resulting appearance of air-bronchograms.
