Collagen-Vascular Disease Associated With Interstitial Lung Disease Differential Diagnoses
- Author: Arshad Ali, MD; Chief Editor: Zab Mosenifar, MD more...
Diagnostic Considerations
Proper diagnosis of interstitial lung disease (ILD) in persons with collagen-vascular disease (CVD) is important. In most cases, treatment is not very successful, and the medications themselves can cause ILD.
Methotrexate-induced pulmonary toxicity can manifest as an acute onset of fever, dyspnea, hypoxia, and patchy interstitial infiltrates, making it indistinguishable from rheumatoid arthritis (RA)-related ILD. The presence of lymphocytes in bronchoalveolar lavage (BAL) fluid, granuloma in lung biopsy specimens, and peripheral eosinophilia can distinguish methotrexate toxicity from RA-related ILD.
In addition to the conditions listed in the differential diagnosis, other problems to be considered include the following:
- Human immunodeficiency virus
- Antiphospholipid antibody syndrome
- Undifferentiated connective-tissue disease
Differential Diagnoses
- Chronic Obstructive Pulmonary Disease
- Coal Worker's Pneumoconiosis
- Diaphragmatic Paralysis
- Drug-Induced Pulmonary Toxicity
- Hypersensitivity Pneumonitis
- Lymphocytic Interstitial Pneumonia
- Pulmonary Fibrosis, Idiopathic
- Pulmonary Fibrosis, Interstitial (Nonidiopathic)
- Pulmonary Hypertension, Primary
- Restrictive Lung Disease
- Sarcoidosis
- Silicosis
