Abstract: Objective To explore the clinical and imaging features of pulmonary embolism (PE)in children with mycoplasma pneumonia (MP).Methods The clinical features,imaging manifestations and laboratory data of 6 children with MP complicated by PE were reviewed retrospectively.Results 6 cases of children were admitted with chief complaints of fever and cough,the D-dimer levels were increased obviously.Consolidation was observed in 4 cases in the right lower lobe combined with pleural effusion and in 2 cases in the left lobe,which showed homogeneous enhancement.Filling defect of pulmonary artery was observed in 1 case,and other 5 cases showed sparse pulmonary vascular in consolidation area.D-dimer returned to normal level and consolidation was absorbed after anticoagulation therapy.Conclusion MP combined with PE in children is rare,and the positive detection rate of pulmonary artery angiography is low.PE should be considered when MP continues to deterioration after anti-infection treatment,even though there is no typical imaging findings of PE.
