Congenital lung lesions: a radiographic pattern approach

Area of Science:

• Pediatric Radiology
• Thoracic Imaging
• Congenital Abnormalities

Background:

• Congenital lung malformations (CLMs) are diverse and can present with similar imaging findings.
• Neonatal diagnosis of CLMs poses challenges due to overlapping appearances and co-occurrence.

Purpose of the Study:

• To review the multimodality imaging features of common CLMs.
• To categorize CLMs based on archetypal radiographic patterns.
• To highlight important imaging mimickers of CLMs.

Main Methods:

• Review of multimodality imaging (e.g., radiography, CT, MRI) of congenital lung malformations.
• Categorization of malformations based on four primary radiographic archetypes: hyperlucent lung, pulmonary cysts, focal opacity, and normal radiograph.
• Inclusion of common imaging mimickers for comparative analysis.

Main Results:

• Archetypal radiographic patterns can significantly narrow the differential diagnosis for neonatal lung abnormalities.
• Specific imaging features are associated with distinct congenital lung malformations within each archetype.
• Recognition of imaging mimickers is crucial to avoid misdiagnosis.

Conclusions:

• Understanding archetypal radiographic patterns is essential for accurate diagnosis of congenital lung malformations in neonates.
• Multimodality imaging review, categorized by pattern, aids in differentiating CLMs and their mimics.
• This approach improves diagnostic accuracy in challenging neonatal thoracic imaging cases.
