- Atypical pneumonia,
- Mycoplasma pneumoniae,
- Chlamydophila pneumoniae, and
- Legionella pneumophila.
- often presents with
- milder symptoms
- may not have characteristic imaging findings.
- diagnosis based on a combination of
- clinical presentation,
- laboratory tests, and
- imaging.
- Structures Involved

| Imaging Finding |
Description |
| 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 |
| Pleural Effusion: |
Less common but can occur, especially in severe cases. |
