Lung Ultrasound in Pediatric Pneumonia: Consolidation Signs and Diagnostic Value
Method Foundation: Anatomy and Normal Ultrasound Appearance
According to EFSUMB Core Curriculum (Andersen et al., 2026), the physician must know ultrasound anatomy of the lungs and pleura, as well as normal findings: lung sliding, A-lines, lung pulse, curtain sign, and seashore sign. Knowledge of normal appearance and localization of specific artifacts and landmarks is a prerequisite for correct interpretation.
Ultrasound Signs of Consolidation in Pneumonia
According to EFSUMB Core Curriculum (Andersen et al., 2026), signs of pathology on the side of visceral pleura and lungs include:
- B-lines as a focal pattern or as manifestation of interstitial syndrome;
- pleural thickening;
- pleural fragmentation;
- comet tail artifacts;
- consolidation;
- air bronchogram;
- fluid bronchogram.
Pneumonic consolidation is characterized by consolidation itself with air and/or fluid bronchogram within its structure, as well as focal pattern of B-lines in the adjacent zone.
Assessment of Pleura and Pleural Spaces
According to the same document, it is necessary to know ultrasound signs of pathology of parietal pleura and pleural spaces: pleural thickening, calcifications, effusion, and pneumothorax (with lung point and barcode sign signs). Assessment of pleural effusion is important in complicated pneumonia course.
Diagnostic Value vs Radiography
No direct comparative quantitative comparison of ultrasound and radiography is provided in the given fragments. [clarify: data on sensitivity/specificity of ultrasound vs radiography in pediatric pneumonia]
Safety
Issues of safe application of lung ultrasound, including in newborns in ICU conditions, are discussed in ECMUS/EFSUMB recommendations (Wolfram et al., 2023).
Frequently asked questions
What ultrasound signs indicate lung consolidation?
According to EFSUMB Core Curriculum (Andersen et al., 2026) — consolidation itself, air bronchogram, and fluid bronchogram.
What findings are considered normal on lung ultrasound?
Lung sliding, A-lines, lung pulse, curtain sign, and seashore sign.
How is pneumothorax detected on lung ultrasound?
By signs of parietal pleura pathology — lung point and barcode sign (EFSUMB Core Curriculum, 2026).
What do B-lines mean in pneumonia?
B-lines can be a focal pattern or manifestation of interstitial syndrome; focal pattern accompanies the consolidation zone.
Is ultrasound more informative than radiography in pediatric pneumonia?
Direct comparison is not provided in the given fragments. [clarify]
