Post 08 - Multifocal Peribronchovasular Consolidation

52-years old came for a CT chest.

The CT shows peribronchovascular areas of consolidation with air bronchograms (arrows).

This is characteristic asbestos exposure related pleural disease.

This is an organizing pneumonia (OP) pattern, which needs to be further investigated for etiology.

However, this type of OP pattern itself has multiple differentials including

1. Lymphoma
2. IgG4-related disease
3. Vasculitis

This pattern is hence consistent with ANCA-associated vasculitis presenting with peribronchovascular areas of consolidation.
