Chest radiography imaging manifestations of children with community-acquired pneumonia caused by common pathogens

doi:10.3877/cma.j.issn.1673-5250.2022.01.002

Community-acquired pneumonia (CAP) is one of the most important causes of death in children younger than 5 years old, which contributes large disease burden to both families and society. Multiple pathogens of CAP cause different characteristics in epidemiology, susceptible population, clinical and imaging manifestations. With high diagnostic value in CAP, chest radiography(CR) is cost-efficient and rapid, which can monitor dynamically. The author intends to expound the latest research progresses of clinical characteristics and CR imaging features of children with CAP caused by three kinds of pathogens: ①viruses as causes of CAP including respiratory syncytial virus (RSV), adenovirus, influenza (Flu), and parainfluenza viruse (PIV); ②bacteria as causes of CAP including Streptococcus pneumoniae (SP), Staphylococcus aureus (SA), Haemophilus influenzae (HI), Escherichia coli (EC), Klebsiella pneumoniae (KP), Pseudomonas aeruginosa (PA); ③ atypical pathogens as causes of CAP including Mycoplasma pneumoniae (MP), Chlamydia pneumoniae (CP), Legionella pneumophila (LP), in order to provide reference for clinical auxiliary diagnosis and early treatment, and to look forward to clinical prospect of CR in diagnosis and treatment of different types of CAP.
