PurposeThe aim of this study is to describe some radiological features in the newborns with microcephaly caused by Zika virus infection during pregnancy.MethodsWe radiologically analyzed 13 cases of newborns with microcephaly born to mothers who were infected by the Zika virus in the early stage of pregnancy.ResultsThe most frequently observed radiological findings were microcephaly and decreased brain parenchymal volume associated with lissencephaly, ventriculomegaly secondary to the lack of brain tissue (not hypertensive), and coarse and anarchic calcifications mainly involving the subcortical cortical transition, and the basal ganglia.ConclusionsAlthough it cannot be concluded that there is a definitive pathognomonic radiographic pattern of microcephaly caused by Zika virus, gross calcifications and anarchic distribution involving the subcortical cortical transition and the basal ganglia, in association with lissencephaly and in the absence of hypertensive ventriculomegaly, are characteristic of this type of infection.
Head wounds caused by firearms in newborns are an under-studied phenomenon in Latin America due to either the low frequency of such events or inadequate documentation. Nonetheless, a progressive increase is noted, with different frequencies reported for different geographic areas. We present the case of a 28-day-old newborn who suffered traumatic brain injury from a gunshot wound stemming from urban violence. This is one of the youngest patients reported with this type of head trauma in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
