The chest film also showed mild cardiomegaly, mild basilar strandy densities with associated thickening of the bronchial markings, and an enlarged main pulmonary artery and central hilar vessels consistent with pulmonary hypertension. Minimal perihilar pulmonary hazy density suggests early edema.
Pleural effusions are absent.
Causes of pulmonary hypertension have different mechanisms. The following are views of a CT scan taken in October, 1997. Small subpleural consolidations are seen in the lateral left upper lobe. Mild bronchial wall thickening is present. In the mid and central lung, there is enlargement of the pulmonary arteries.
