Abstract
Pneumonia remains one of the leading causes of mortality in children under five years of age, particularly in low- and middle-income countries. Although chest radiography is the standard diagnostic method, it has limitations such as radiation exposure and reduced sensitivity in certain cases. In this context, lung ultrasound has emerged as an effective, safe, and accessible diagnostic tool, This method allows for the identification of typical pneumonia signs such as consolidations and dynamic air bronchograms, with high sensitivity (96%) and specificity (93%), according to recent studies. Furthermore, its portability and ease of use make it suitable for clinical settings with limited resources. Thoracic ultrasound thus represents a valuable diagnostic alternative in pediatric care.
