- Thickened interlobular septa
- thickened peribronchial interstitium
- thickened fissures compatible with subpleural edema and/or interlobar effusions
- trace dependent pleural effusions
- ground-glass opacity influenced by gravity with increased opacity in the dependent portion of the secondary lobules and the lobes of the lung,
- normal heart chambers, major arteries, systemic veins
Case Discussion
The septal lines and ground-glass opacity are most suggestive of pulmonary edema. Be sure to look at the PA chest X-ray and the coronal CT images to better appreciate the appearance of Kerley B lines.
Normal heart size is compatible with pulmonary edema. Diastolic dysfunction and non-cardiogenic pulmonary edema are examples of this.
