Post-Pneumonic Poor Air Entry

Hello, a 2 years old male presented with typical picture of lobar pneumonia, examination showed localized crepitation with no air entry in the right lower lobe and CXR showed right lower zone infiltration, after 10 days with antibiotic treatment, the fever subsided but there is still poor air entry, what could be the possible cause ? Thank You
