Childhood interstitial lung disease more prevalent in infancy: a practical review

Area of Science:

• Pediatric Pulmonology
• Radiology
• Medical Imaging

Background:

• Childhood interstitial lung disease (chILD) encompasses rare, chronic pediatric lung disorders.
• These conditions impair gas exchange and show diffuse imaging abnormalities.
• Certain chILD types are more common in infants and young children.

Purpose of the Study:

• To familiarize pediatric radiologists with chILD subtypes prevalent in infancy.
• To highlight clinical, histopathological, and CT features aiding diagnosis.
• To potentially reduce the need for lung biopsies in pediatric patients.

Main Methods:

• Review of clinical presentations of infant chILD.
• Analysis of histopathological findings in pediatric interstitial lung diseases.
• Evaluation of computed tomography (CT) imaging characteristics.

Main Results:

• Identified key features of infant-prevalent chILD, including developmental disorders, growth abnormalities, and undefined etiologies.
• Detailed specific conditions like surfactant dysfunction mutations.
• Emphasized the role of imaging in suggesting diagnoses.

Conclusions:

• Recognizing specific clinical and imaging patterns is crucial for diagnosing infant chILD.
• Radiologists can play a key role in guiding diagnosis and management.
• Familiarity with these disorders can improve diagnostic accuracy and patient care.
