Interstitial disease associated with connective tissue disease and vasculitis

Area of Science:

• Rheumatology
• Pulmonology
• Radiology

Background:

• Systemic autoimmune diseases are complex and heterogeneous.
• Pulmonary complications, particularly interstitial lung disease, are significant.
• Interstitial lung disease in these conditions mimics idiopathic interstitial pneumonia radiopathologically.

Purpose of the Study:

• To highlight the importance of interstitial lung involvement in systemic autoimmune diseases.
• To emphasize the role of high-resolution computed tomography (HRCT) in diagnosis and prognosis.
• To underscore the necessity of collaborative diagnosis and treatment.

Main Methods:

• Review of radiopathologic patterns of interstitial lung disease in systemic autoimmune diseases.
• Emphasis on high-resolution computed tomography (HRCT) as the gold-standard imaging technique.
• Discussion of common presentations, such as nonspecific interstitial pneumonia.

Main Results:

• Interstitial lung disease shares radiopathologic features with idiopathic interstitial pneumonia.
• HRCT is essential for disease identification, classification, extent determination, and prognosis.
• Nonspecific interstitial pneumonia is the most frequent pattern observed.

Conclusions:

• Accurate diagnosis and prognosis of interstitial lung disease in autoimmune conditions rely on HRCT.
• Multidisciplinary collaboration among radiologists and other specialists is vital.
• Integrated treatment strategies are necessary for optimal patient outcomes.
