FIG. 36.6 Bronchopulmonary Sequestration With Effusion. (A) Axial image of the fetal chest demonstrates a left pleural effusion with
moderate mediastinal shift to the right. (B) Axial and (C) coronal color Doppler images show a systemic feeding vessel coursing into the echogenic
left lower lobe. (D) Sagittal T2-weighted MRI shows the high signal intensity left lower lobe mass with a moderate surrounding effusion.
follow-up is required because air trapping and respiratory distress
may necessitate lobar resection. 102
PLEUROPULMONARY BLASTOMA
Pleuropulmonary blastoma is a rare primary neoplasm originating
from the pleuropulmonary mesenchyme (previously called
pulmonary blastoma or malignant mesenchymoma). 104 hree
pleuropulmonary blastoma types have been described: type I
(exclusively cystic), type II (mixed cystic and solid lesion), and
type III (predominantly solid mass). 105
Seen on ultrasound, pleuropulmonary blastoma appears as
a complex macrocystic lesion in the chest, indistinguishable from
a CPAM. Features that help diferentiate pleuropulmonary
blastoma from CPAM include a positive family history, presence
of multifocal lesions, and association with pleural efusion. 106
