CTICasesChronic Thromboembolic Pulmonary Hypertension
Imaging findings
Chest radiograph and CT show dilated main pulmonary arteries, right ventricular hypertrophy, and a large eccentric filling defect in the left lower lobe pulmonary artery. Markedly dilated bronchial and intercostal artery collaterals are present, with mosaic lung perfusion.
Key takeaways
Chronic thromboembolic pulmonary hypertension (CTEPH) results from organized thrombi obstructing the pulmonary arteries. CT features include eccentric thrombi, webs, and vascular pruning. Hypertrophy of bronchial and systemic collaterals (intercostals) provides retrograde flow to hypoxic segments.
