Prenatal ultrasonographic diagnosis and outcome of congenital lung abnormal lesion / 中华超声影像学杂志

ABSTRACT

Objective To determine sonographic features and outcome of fetal lung abnormal lesions. Methods Blood supply of the lesion, fetus hydrops and other extra-lung anomalies should be evaluated by color Doppler flow image(CDFI) when abnormal lesion was detected in fetus lung during routine scanning. The fetus with lung abnormal lesion without hydrops at the first time scanning should be monitored by ultrasound in every four to six weeks. Results Forty cases fetus presented lung abnormal lesions, which included 21 cases with hyperechogenic solid masses,15 cases with cystic-solid mixture masses,4 cases with cystic masses. Lesions of 8 cases were demonstrated systemic arterial blood supply arising from the aorta on CDFI and the diagnosis of pulmonary sequestration (PS) were suggested. Seventeen cases lesion that had small size or decreased or disappeared or remained stable in size with gestational age developing had normal neonate. Conclusions CDFI is very useful in detecting abnormal lesion of the fetal lung and differentiating pathology and evaluating the prognosis. The outcome of isolated lung lesion without hydrops and mediastinal shift that decreased or disappeared or remained stable in size had a good prognosis.
