RESUMO
Objective To investigate the diagnosis,operation and outcomes of congenital cystic lung lesions in children.Methods Fifty-two children with congenital cystic lung lesions were collected.The clinical data s were analyzed including manifestations,lesion characteristics,imaging,histopathology,diagnosis,surgical treatment methods and short-term pulmonary functions.Results There were 33 male and 19 female,aged from 1 day to 159 months,their median age was 3.67 months.Five cases were neonates.There were 42 cases of bronchogenic cyst,6 cases of pulmonary sequestration,3 cases of congenital lobar emphysema and 1 case of congenital cystic adenomatoid malformation.The cases commonly manifested by lung infections.Of 52 cases,61.5％ were diagnosed after the first onset of lung infection,21.1％ for repeated lung infections and 17.3％ with no symptom.Right lower lung was the most common lesion site and the cases accounted about for 36.5％.Multiple gas cysts were the most common imaging findings accounting about for 42.3％.The pathologic examination of all cases showed bronchogenic cysts.The missed diagnosis rate was 17.3％.The misdiagnosis rate was 24.9％,which of bronchogenic cyst cases was 19.2％.All cases received the lobectomy without death.Conclusions The preoperative diagnosis of congenital cystic lung lesions is mostly based on imaging findings.Clinical manifestations are useful for identifying early the lesions.The preoperative diagnosis may be easily missed or incorrectly done.Pathological findings contribute to make a definite diagnosis.The surgery effect is satisfactory and the outcome is good.
