Chest imaging characteristics of hand-foot-mouth disease in children / 中华放射学杂志

ABSTRACT

Objective To study radiological characteristics of hand-foot-mouth disease(HFMD) in children. Methods The chest X-ray films of 1295 children patients of HFMD were analyzed,for the general X-ray manifestations and the evolution. Results A total of 1427 films was obtained from all patients, in which 1203 cases were normal and 224 cases were abnormal. The interstitial changes characterized the abnormal group, mainly as increased and vague lung markings, increased hilar shadows (137 cases).The parenchyma changes appeared as patchy exudative shadows(49 cases). Short-term dynamic observation was applied in 62 cases, 38 cases pulmonary disease progression manifested as normal and the interstitial type changing into the parenchyma type and the mixed type, the localized type changing into the diffuse type. Conclusions Most children patients of HFMD showed normal chest films, while the abnormal patients were characterized by interstitial and parenchyma pulmonary edema. Serial chest X-ray examination and short-term dynamic observation were important to identify the severe cases and assess patients' condition.
