Background:Pneumonia is defined as "new lung infiltrates plus clinical evidence that the infiltrate is of an infectious origin, which include the new onset of fever, purulent sputum, leukocytosis, and decline in oxygenation. LUS has a number of advantages it is easy to do at a child's bedside, takes little time to perform and interpret the results, allows a close follow-up, and avoids the use of ionising radiation.
Objective: Our main objective in this study is to validate the value of lung ultrasound in diagnosis of pneumonia in children in comparison with chest radiography in Sohag University Hospital.
Methods: This adescriptive cross-sectional study of children clinically diagnosed as pneumonia conducted on 70 cases they were classified into four groups according to the age of patients; group I from Results: LUS findings among studied population, consolidation was seen in 66 cases of 70 (94.29%),30 cases of them were in the right lung, 22 were in the left one (33.33%) and 14cases were bilateral (21.21%).pleural effusion was detected in 28 cases (40%) and cannot be detected in 42 patients (60%).comparison between LUS findings and diagnosis of pneumonia ,there was no statistical significant difference between LUS findings and diagnosing pneumonia this indicated that LUS is helpful and accurate in diagnosis of pneumonia in children .
Conclusion: chest ultrasound was accurate in the diagnosis of pneumonia and we suggest that LUS is an alternative tool to chest radiography in the diagnosis of pneumonia in children and that the follow up of patients with pneumonia by LUS can reduce the exposure of children to ionizing radiation.
