Pediatric Pulmonary Hemosiderosis

  • Etiology: in pediatrics most common etiology is idiopathic, repeated alveolar hemorrhage -> hemosiderin in macrophages in alveolar wall, fibrosis, severe anemia
  • Imaging: start with diffuse alveolar infiltrates, later fibrotic changes + honeycombing

Radiology Cases of Pulmonary Hemosiderosis

CXR of pulmonary hemosiderosis
Initial CXR AP (left) shows diffuse alveolar infiltrates primarily in the upper lobes. CXR AP obtained a week later (right) shows resolution of the findings.
