CTICasesPulmonary Parenchymal Extramedullary Hematopoiesis
Imaging findings
Chest CT shows chronic, stable, diffuse ground-glass opacities with focal lobular sparing in a patient with myelofibrosis and abnormal bones, consistent with pulmonary extramedullary hematopoiesis.
Key takeaways
Extramedullary hematopoiesis can rarely involve the lung parenchyma directly. It presents as chronic, stable, diffuse ground-glass opacities with lobular sparing, and must be differentiated from chronic edema or alveolar proteinosis.
