2024年8月25日 · Radiographic features of congenital Zika viral infection have been reported on ultrasound, CT and MRI, and most result from a negative effect on brain development. Congenital Zika vial infection has been shown to cause various brain abnormalities affecting both grey and white matter and ventricular size 4,5 .

Neurologic manifestations of Zika virus infection are primarily seen as microcephaly and GBS. The imaging examinations including fetal ultrasound, CT, and MRI are quite helpful to diagnose and evaluate this disease. MRI can identify more associated abnormalities than CT and should be the first choice of investigation where available.

2017年5月9日 · In CT and MRI studies of congenital Zika syndrome, the findings most commonly reported are a reduction in head circumference and a dramatic reduction in brain volume, both of which are indicative of microcephaly and are more common when the infection occurs in the first trimester of pregnancy, with a risk of 1–13% (34-41). Microcephaly can be ...

Magnetic resonance imaging (MRI) offers a noninvasive diagnostic tool to complement the clinical neurological assessment of infants exposed to ZIKV in utero, those with microcephaly as well as those who are less affected (normocephalic).

ZIKV-exposed infants exhibited smaller volumes in the amygdala, a brain region primarily involved in emotional and behavioral processing. This brain MRI finding may lead to poorer behavioral outcomes and warrants long-term monitoring of pediatric cases of infants with gestational exposure to Zika virus as well as other neurotropic viruses.

2016年4月13日 · The features on magnetic resonance imaging (MRI) have not been described in children born with microcephaly. 18 We describe the brain imaging (CT and MRI) features as well as principal clinical findings of children with microcephaly and presumed congenital infection related to the Zika virus during the epidemic in Pernambuco, Brazil.

2024年11月7日 · In infants exposed to ZIKV perinatally, the frequency of classic and atypical findings on brain MRI seems to be associated with the neurological status. Brain MRI is an important diagnostic tool in the evaluation and monitoring of patients with congenital infection, because intracranial changes othe …

2016年8月23日 · Imaging examinations included 12 fetal magnetic resonance (MR) examinations, 42 postnatal brain computed tomographic examinations, and 11 postnatal brain MR examinations. Images were reviewed by four radiologists, with final opinion achieved by means of consensus.

2016年4月13日 · Main outcome measures: Types of abnormalities and the radiological pattern of lesions identified on CT and MRI brain scans. Results: Six of the 23 children tested positive for IgM antibodies to Zika virus in cerebrospinal fluid. The other 17 children met the protocol criteria for congenital infection presumably associated with the Zika virus ...

2019年1月23日 · We reviewed 102 cases of children who were diagnosed with microcephaly at birth and who had gestational exposure to ZIKV during the outbreak. We describe the clinical, neuroimaging, and neurophysiological findings. Most mothers (81%) reported symptoms of ZIKV infection, especially cutaneous rash, during the first trimester of pregnancy.
