Congenital overinflation: prenatal MRI and US findings and outcomes.

Objective: The purpose is to describe fetal MR and US findings of congenital overinflation (CO) and to correlate with postnatal outcome.

Methods: Two radiologists reviewed fetal MR and US images in 25 fetuses diagnosed with CO. Lesion size, appearance, location, and presence of hydrops were documented.

Congenital peribronchial myofibroblastic tumor: prenatal imaging clues to differentiate from other fetal chest lesions.

We present a prenatal case of congenital peribronchial myofibroblastic tumor referred as a congenital pulmonary airway malformation (CPAM) with hydrops and polyhydramnios at 30 weeks' gestational age. US and fetal MRI findings did not fit with the referral diagnosis, raising the possibility of intrinsic lung tumor. Fetal hydrops worsened and the baby was successfully delivered by ex utero intrapartum treatment (EXIT) to resection at 31 weeks' gestational age.

Prenatal imaging of amniotic band sequence: utility and role of fetal MRI as an adjunct to prenatal US.

Background: Amniotic band sequence and its US manifestations have been well-described. There is little information, however, regarding the accuracy and utility of fetal MRI.

Objective: To describe the MRI findings in amniotic band sequence and to compare the diagnostic accuracy of MRI and US.
