Pneumonia is a prevalent disease with considerable morbidity and mortality among the pediatric population. Early diagnosis and swift commencement of the correct treatment are vital for a favorable clinical outcome.

Along with history-taking and clinical examination, imaging modalities commonly used, lung ultrasound provides a bedside, less invasive, radiation-free alternative to diagnose pneumonia when compared with other images such as chest x-ray (CXR) and computed tomography (CT) scan.

It is therefore of the utmost magnitude to inspect the evidence of its accuracy and reliability in the diagnosis of this condition.

The goal of this study is to look into the available data supporting the use of lung ultrasound in the diagnosis of juvenile pneumonia, its relevance in distinguishing between viral and bacterial diseases, and its superiority as compared to other diagnostic methods.

As mentioned, early detection and differentiation of the type of pneumonia can reduce unnecessary antibiotic prescriptions and provide patients with a better prognosis, as well as the ability to predict the course of the disease and the need for advanced care or the development of complications.

An extensive literature search of two popular online medical websites (PubMed and Embase) was conducted in this review, concentrating on studies that examined the role of lung ultrasound in the diagnosis of pediatric pneumonia published in the last five years.

Only studies published in the English language were included in this review.

With high sensitivity and specificity, lung ultrasound appeared to be a promising tool not only for pediatric pneumonia diagnosis, but also for treatment guidance and disease follow-up, especially when combined with clinical presentation and laboratory findings.
