小儿支原体肺炎的X线诊断

分析并讨论了40例小儿支原体肺炎的X线征象及其在早期诊断中的价值.结果表明,病变位于一侧肺24例,两侧肺16例;下肺82.5%,上肺35.0%.全部示肺间质炎症,82.5%伴有肺实质浸润.若3岁以上小儿出现高热、剧烈干咳症状,肺部体征较少而胸片改变显著,胸片示肺门影增大且与间质性网状结节影和(或)实质性片状影相连,即应高度怀疑本病,行血清冷凝集试验便可明确诊断,给予及时治疗.提示X线检查对小儿支原体肺炎的早期诊断有重要意义.

RADIOLOGIC DIAGNOSIS OF MYCOPLASMA PNEUMONIA IN CHILDREN

The chest radiographs of 40 child patients with serologically proven mycoplanma pneumonia were reviewed. The result showed that the lower lobes (82.5%) were involved more frequently than the upper lobes (35.0%). Unilateral involvement was seen in 24 cases. All in the series showed pulmonary interstitial changes in a widespread reticonodular pattern often extending from the hilum. 82.5% of them were associated with lobar or segmental consolidations. Perihilar interstitial infiltrates accounted for 87.5 % which were connected mostly with the pulmonary interstitial changes and/or the consolidations of parenchymal infiltrates. If the chest films of a child older than 3 years shows the above radiographic picture and there are clinically high fever and severe dry cough, mycoplasma pneumonia should be strongly suspected. The diagnosis can be early confirmed by serum cold agglutinin test and the effective treatment should be given in time.
