• related: ILD Interstitial Lung Disease or Diffuse Parenchymal Lung Disease
• tags: #literature

---

• HP hypersensitivity pneumonitis is divided into fibrotic and nonfibrotic types

Image findings

• image findings in hypersensitivity pneumonitis include GGO, centrilobular micronodules, and mosaicism

Diagnosis

• diagnosis of HP is in imaging and BAL with high lymphocyte count

Disease associations

• MAC infection can induce hypersensitivity pneumonitis in patients with exposure to hot tube water
• mulch pneumonitis is hypersensitivity in CGD patients
• pool, hot tub, mold, cheese, beer

Treatment

• steroid taper for HP hypersensitivity pneumonitis

Literature Note

• Fundamentals of High Resolution Lung CT
• fibrotic HP management
