Clinical analysis of 96 cases of congenital cystic lung lesions in children

Abstract

Objective: To summarize the diagnosis, clinical manifestations, treatment and prognosis of congenital cystic lung lesions. Methods: A retrospective study described the clinical course of 96 patients (46 female and 50 male) diagnosed with congenital cystic lung lesions treated at the Tianjin Children's Hospital from January 2010 to March 2019. The clinical findings, imaging examinations, pathological findings, treatment and follow-up were analyzed. Results: Totally 96 patients (aged from 4 days to 13 years) with congenital cystic lung lesions were included in this study. Eighty-six patients (90%) were diagnosed when they had cough and fever symptoms. Forty (42%) patients exhibited congenital cystic adenomatoid malformation, 30 underwent surgical excision, two were at emergency operations and one dead. There were 12 (13%) patients with pulmonary sequestration and four were surgical treated. Twelve (13%) patients with bronchogenic cyst were included and 4 were surgically treated. There were 3 (3%) patients with congenital lobar emphysema and one was surgically treated. Another patient with pneumothorax was operated in other hospital 2 months after discharge. Twenty-nine (30%) patients with unclassified congenital cystic lung lesions could not be definitively diagnosed by CT. Some of them were difficult to be distinguished from necrotizing pneumonia. Finally, 2 patients were diagnosed as necrotizing pneumonia after 6, 10 months follow-up. After operation 37 out of 39 patients recovered well. Conclusions: The diagnosis of congenital pulmonary cystic disease depend on imaging and pathological examination. Most patients are diagnosed when they have respiratory tract infection. The main clinical manifestations are cough and fever. The prognosis of operative management is good.
