IPFI

Clinical manifestations

multi-system injuries

dry cough and fever,no specific

Laboratory tests

Serum IgG4 elevation

CRP and (or) PCT elevation,G/GM positive

Imaging

nodules, multiple ground glass opacities (GGO),alveolar interstitial type, and bronchovascular type

nodules, consolidation and ground-glass opacity(GGO)

Pathology

Mainly IgG4

With plasma cell infiltration and often with interstitial damage

fungal spores with hyphae can be observed, pulmonary fibrosis and inflammatory cell infiltration

Treatment protocol
