In 1947, Zika virus (ZIKV) was first discovered in Monkeys, in Zika Forest, in Uganda, Africa. Five years later, (1952) the first human Zika infection was detected in Nigeria, Africa. After this date, only sporadic cases happened, until the first 3 epidemics occurred, all outside Africa. The first epidemic was in Yap Island in 2007, the second in French Polynesia in 2013, and the third in 2015 in the northeast of Brazil, and then the spread to the Americas in 2015 and 2016. However, it was only after the epidemic in the northeast of Brazil, in the first half of 2015, that many babies were born with microcephaly in the second semester of that same year and in 2016. Until now, every year, some babies are still born with congenital ZIKV syndrome (CZVS).
The objective of this article is to describe infrequent and rarely discussed imaging (computed tomography and magnetic resonance imaging) findings of CZVS, in addition to those classically described such as a simplified gyral pattern, ventriculomegaly, corpus callosum dysgenesis, craniofacial disproportion, and redundant scalp, thus suggesting an increase in the spectrum of neurological findings related to the syndrome.
1947 年,寨卡病毒(Zika virus,ZIKV)首次在非洲乌干达的 Zika 森林中的猴子体内被发现。五年后(1952 年),在非洲的尼日利亚首次检测到人类感染寨卡病毒。此后,仅零星发生病例,直到发生了前三次疫情,均发生在非洲以外地区。第一次疫情发生在 2007 年的雅蒲岛,第二次发生在 2013 年的法属波利尼西亚,第三次发生在 2015 年巴西东北部,随后于 2015 年和 2016 年传播到美洲。然而,直到 2015 年巴西东北部疫情爆发后,同年下半年和 2016 年才出现许多婴儿出生时患有小头畸形。截至目前,每年仍有一些婴儿出生时患有先天性寨卡病毒综合征(congenital Zika virus syndrome,CZVS)。
本文的目的是描述 CZVS 不常见且很少讨论的影像学(计算机断层扫描和磁共振成像)表现,除了经典描述的表现,如简化的脑回模式、脑室扩大、胼胝体发育不良、颅面比例失调和冗余头皮,这提示与该综合征相关的神经学表现谱增加。
