Cytomegalovirus-related fetal brain lesions: comparison between targeted ultrasound examination and magnetic resonance imaging.

Objective: To evaluate the relative contributions to the diagnosis of fetal brain abnormalities of targeted ultrasound examination and magnetic resonance imaging (MRI) in fetuses infected with cytomegalovirus (CMV).

Methods: This was a retrospective analysis of targeted brain ultrasound examination and fetal brain MRI performed in fetuses diagnosed with CMV infection following proven maternal primary infection. The prenatal findings were compared with findings from postnatal transfontanellar ultrasound examination during the first week following delivery or from postmortem when the pregnancy was terminated.

Prenatal diagnosis of neurofibromatosis type 1: sonographic and MRI findings.

Prenatal ultrasound and magnetic resonance imaging (MRI) demonstrated a large oropharyngeal tumor, and cardiac and cranial abnormalities consistent with neurofibromatosis type 1 (NF1) in a third-trimester fetus, which were confirmed on postmortem examination. Sonographic features of NF1 are generally nonspecific; MR examination provided significant additional information, facilitating prenatal diagnosis.

[Discovery of caput succedaneum after premature rupture of the membranes at 28 weeks gestation].

Caput succedaneum often occurs at birth, especially in vaginal delivery. It is a cranial subcutaneous serohematic extravasation, with a good prognosis, and spontaneous regression is the rule within a few days. In the literature, it has been mainly described in the neonatal period.
