Reticular shadowing - Fibrosis
- Pulmonary fibrosis causes reticular (net-like) shadowing of the lung peripheries which is typically more prominent towards the lung bases
- It may cause the contours of the heart to be less distinct or ‘shaggy’
- Chest X-rays can be helpful in monitoring the progression of pulmonary fibrosis
Fibrosis
- (Same patient as image above – 20 months later)
- As the disease progresses the fibrosis (lung scarring) becomes more widespread and leads to lung volume loss
- In the mid-clavicular lines on each side, the diaphragm is positioned above the level of the 4th and 5th ribs on the right and left respectively
- Compare with the image above which showed normal lung volume
