CTICasesPulmonary Alveolar Proteinosis
Imaging findings
The radiograph shows bilateral, patchy, and extensive consolidation. CT imaging reveals ground glass opacities and areas of consolidation, with the characteristic "crazy paving" pattern observed particularly in the right middle lobe. These findings are consistent with primary alveolar proteinosis, though the distribution may not always be perfectly symmetric. The patient was also GM-CSF antibody positive.
Key takeaways
Pulmonary alveolar proteinosis is characterized by distinctive radiographic and CT findings, including bilateral patchy consolidation, ground glass opacities, and the "crazy paving" pattern. It is frequently associated with GM-CSF antibody positivity, and whole-lung lavage is a common treatment.
