    • imaging.
  • Structures Involved
    • bronchovascular
    • alveoli
    • interstitium
    • Patchy Involvement

    Peribronchial and Perivascular Distribution: Infiltrates around bronchovascular bundles.
    Ground-Glass Opacities (GGOs): Areas of partial airspace filling.
    Patchy Involvement: Patchy rather than lobar consolidation.
    Ground-Glass Opacities (GGOs): Areas of partial airspace filling.
    Segmental or Multifocal Involvement: Involvement of multiple lung segments or multifocal areas
