Abstract

Objective: The objective of this study is to determine the main neuroimaging findings of microcephalic newborns with possible Zika virus (ZIKV) intrauterine infection using transfontanellar cranial ultrasound. Methods: We performed a retrospective study to describe the main neuroimaging findings in newborns with microcephaly and possible association with congenital ZIKV infection. Microcephaly was defined in the postnatal period using transfontanellar cranial examination which was performed using both two- (2D) and three-dimensional (3D) ultrasound. Results: One hundred and fifty newborns with microcephaly were identified during the study period. The mean ± (standard deviation - SD) of cephalic perimeter was 28.5 ± 4.2 cm (range, 25–38 cm). Transfontanellar neuroimaging patterns detected cerebral calcifications, neuronal migrational abnormalities, dysgenesis of the corpus callosum, and cerebellar atrophy in 34.9%, 31.1%, 26%, and 16.2%, respectively. Hydrocephalus was seen in 28% of overall newborns. A history of maculopapular rash was present in almost half of the mothers (46.1%). Conclusion: Neuroimaging patterns by means of transfontanellar ultrasound are accurate and diagnostic investigations of brain pathology in newborns affected by microcephaly and possible intrauterine ZIKV infection.
