Evaluation of diffuse pulmonary infiltrates

  • Differential can be split into benign diseases and malignant diseases.
  • Malignant disease is more likely to have multiple pulmonary nodules greater than 1 cm while those less than 5mm are more likely to be associated with benign disease.
  • Benign causes:
    • Abscesses
    • Septic emboli
    • Fungal and parasitic infections
    • Tuberculosis and MAC
    • Vasculitides (GPA most common), RA, sarcoidosis, hypersensitivity pneumonitis
    • Pneumoconioses
  • Malignant causes:
    • Solid organ tumors
      • Most
    • Non-Hodgkin lymphoma
    • Kaposi’s sarcoma in HIV+ patients
  • Typically sarcoidosis, lymphomas, tuberculosis, fungal diseases, pneumonconioses and malignancies are associated with lymph node enlargement.
