CTICasesPulmonary Venous Occlusive Disease (PVOD) / Pulmonary Capillary Hemangiomatosis (PCH)
Imaging findings
Pronounced mosaicism, areas suggestive of venous infarct/hemorrhage, and macroscopic occlusion of pulmonary veins.
Key takeaways
Diagnosis of PVOD/PCH is challenging and often requires clinical-pathological correlation. While typically associated with poor prognosis and progressive fibrosis, some cases may show atypical responses to anticoagulation, making the underlying etiology (e.g., vasculitis vs. primary venous disease) difficult to confirm.
