Imaging findings
Follow-up chest radiograph shows a "very busy look" to the lungs, a less specific but common finding in hepatopulmonary syndrome (HPS). Thin-section abdominal CT images demonstrate numerous tiny lung vessels extending directly to the pleural surfaces, highlighting the dramatic extent of intrapulmonary vascular dilations characteristic of HPS.
Key takeaways
Hepatopulmonary syndrome is characterized by intrapulmonary vascular dilations and hypoxemia. Chest radiographs can appear busy, while thin-section CT images more clearly demonstrate the diffuse vascular abnormalities, with vessels reaching the pleura, indicative of a severe shunt.
