Usefulness of prenatal magnetic resonance imaging in differential diagnosis of fetal congenital cystic adenomatoid malformation and bronchopulmonary sequestration

Figure 1 At the 25^th week of gestation, congenital cystic adenomatoid malformation was diagnosed by prenatal magnetic resonance imaging and postnatal surgical pathology. A: The lesion was located in the left lung, with a visible empty vessel running from the midline to the lateral down direction; B: The large blood vessel shifted to the right, and heart to the right.

Figure 2 At the 27^th week, bronchopulmonary sequestration was diagnosed by prenatal magnetic resonance imaging and postnatal surgical pathology. A: The lesion was located in the lower left lung, with a visible empty vessel running from the midline to the lateral up direction; B: There were clear boundaries between the lesions and normal lung tissues.
