Abstract：Objective To analyze the imaging features of a group of children's pleuropulmonary blastomas(PPB)and enhance understanding of the disease and reduce misdiagnosis.Methods A retrospective analysis was conducted on the clinical,imaging,and pathological data of 13 children with pathologically confirmed PPB.All 13 cases underwent chest X-ray,CT and enhanced CT,and 2 cases also had MRI examinations.Results Lesions were observed in the right thoracic cavity in 7 cases and the left thoracic cavity in 6 cases,with an average tumor diameter of 7.87±2.48 cm.There were 6 cases of cystic lesions,5 cases of cystic-solid lesions,and 2 cases of solid lesions.On enhanced CT,the cystic areas of the lesions showed no enhancement,while the solid components of cystic-solid and solid lesions exhibited mild-moderate heterogeneous enhancement.5 cases were complicated with pleural effusion,1 with pneumothorax,and 1 with intrapulmonary metastasis.Radiological classification:there were 6 cases of type I,3 cases of type II,and 4 cases of type III.Pathological classification:there were 6 cases of type I,5 cases of type II,and 2 cases of type III.Conclusion The radiological manifestations of PPB are correlated with its pathological type,and its diagnosis requires reliance on pathology and immunohistochemistry.
