儿童手足口病的胸部影像表现

目的 探讨儿童手足口病的胸部影像表现.方法 调查1295例手足口病患儿胸部X线片,分析其影像表现及演变过程.结果 1295例手足口病患儿共行1427例次胸部X线检查,其中1203例次X线无异常发现,224例次表现异常.异常征象主要表现为以肺纹理增粗模糊、肺门影增大为特征的间质型改变(137例次)和以斑片状渗出阴影为特征的实质型改变(49例次).62例患儿行短期动态观察,38例次病变进展表现为正常和单纯间质型向肺实质型及混合型过渡,局限性向弥漫性病变过渡.结论 多数手足口病患儿胸部X线表现无异常,异常胸部X线表现以肺间质和实质水肿为主要特点,及时的胸部X线检查和短期动态观察对早期发现重症患者、评价病情较为重要.

Chest imaging characteristics of hand-foot-mouth disease in children

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.
