FIG. 33.31 Lymphatic Malformation. (A) Two-dimensional sonogram of left neck mass at 35 weeks showing complex cystic and solid

appearance. (B) Three-dimensional sonogram showing left-sided mass. Coronal (C and D) and sagittal (E) fetal magnetic resonance images show

the complex mass, potentially blocking the airway. (F) The newborn, with large left-sided neck mass, was successfully intubated during delivery

by EXIT (ex utero intrapartum treatment) procedure.

FIG. 33.32 Teratoma. (A) Three-dimensional sonogram at 34 weeks shows a right-sided cervical teratoma. Sagittal (B) and axial (C) T2-weighted

fetal magnetic resonance images. Note visualization of the trachea (arrow), suggesting that the airway would likely be patent at birth.
