The Value of Pre- and Postnatal MRI Monitoring of Cytomegalovirus-Related Brain Lesions

Magnetic resonance imaging (MRI) abilities in pre- and postnatal monitoring of cytomegalovirus-related brain lesions from early prenatal period to infancy are described. Objective of our study is to illustrate the gradual evolution of intracranial abnormalities in a single patient through serial pre- and postnatal MRI. It demonstrates the progress of a cerebral cytomegalovirus infection from fetal to postnatal life with the lack of concordance between prenatal ultrasonography and MRI, and proves the great importance of MRI, being in most cases the only tool for early detection and monitoring of this potentially devastating entity. It was shown that the additional postnatal MRI increases the possibilities in the specific characterization of lesions revealed in the fetus brain, which account for a wide spectrum of different sequences and best spatial resolution of postnatal MRI in comparison with the prenatal one.
