Pulmonary strongyloidiasis

Pulmonary strongyloidiasis refers to changes associated with lung infection due to the parasite named Strongyloides stercoralis. It is endemic to both the tropics and subtropics.

Pathology

Severe cases such as hyperinfection syndrome (HS) and disseminated strongyloidiasis (DS), can involve pulmonary manifestations.

Spectrum of changes that can involve the lung include

• pulmonary infiltrates with eosinophilia
• asthma without infiltrates
• hemoptysis: from alveolar hemorrhage
• hyperinfection syndrome
  •    acute respiratory distress syndrome
  •    lung abscess formation
  •    interstitial infiltrates/fibrosis
  •    cavitary lesions
