ABSTRACT

BACKGROUND AND PURPOSE: Although microcephaly is the most prominent feature of congenital Zika syndrome, a spectrum with less severe cases is starting to be recognized. Our aim was to review neuroimaging of infants to detect cases without microcephaly and compare them with those with microcephaly. MATERIALS AND METHODS: We retrospectively evaluated all neuroimaging (MR imaging/CT) of infants 1 year of age or younger. Patients with congenital Zika syndrome were divided into those with microcephaly at birth, postnatal microcephaly, and without microcephaly. Neuroimaging was compared among groups. RESULTS: Among 77 infants, 24.6% had congenital Zika syndrome (11.7% microcephaly at birth, 9.1% postnatal microcephaly, 3.9% without microcephaly). The postnatal microcephaly and without microcephaly groups showed statistically similar imaging findings. The microcephaly at birth compared with the group without microcephaly showed statistically significant differences for the following: reduced brain volume, calcifications outside the cortico-subcortical junctions, corpus callosum abnormalities, moderate-to-severe ventriculomegaly, an enlarged extra-axial space, an enlarged cisterna magna (all absent in those without microcephaly), and polymicrogyria (the only malformation present without microcephaly). There was a trend toward pachygyria (absent in groups without microcephaly). The group with microcephaly at birth compared with the group with postnatal microcephaly showed significant differences for simplified gyral pattern, calcifications outside the cortico-subcortical junctions, corpus callosum abnormalities, moderate-to-severe ventriculomegaly, and an enlarged extra-axial space. CONCLUSIONS: In microcephaly at birth, except for polymicrogyria, all patients showed abnormalities described in the literature. In postnatal microcephaly, the only abnormalities not seen were a simplified gyral pattern and calcifications outside the cortico-subcortical junction. Infants with normocephaly presented with asymmetric frontal polymicrogyria, calcifications in the cortico-subcortical junction, mild ventriculomegaly, and delayed myelination.

ABSTRACT

Entre 1-janeiro e 30-setembro-1990 foram estudados 77 pacientes com diagnóstico de leptospirose confirmada, laboratorialmente. Apresentaram início súbito dos sintomas 69 (89,61 por cento) pacientes, com febre, cefaléia, calafrios e mialgias. Observou-se envolvimento plurissistêmico quer nos pacientes ictéricos, quer nos anictéricos. O exame neurológico foi anormal em 70(90,91 por cento) pacientes, com achados variáveis e que, embora de caráter transitório, permitiram caracterizar as formas clínicas seguintes: meningoencefalite e polineurite associadas, meningoencefalite, polineurite e hemorragia subaracnóidea

ABSTRACT

Entre 1-janeiro e 30-setembro-1990 foram estudados 77 pacientes com diagnóstico de leptospirose, admitidos no SDIP/UFPE. O exame neurológico foi anormal em 70 (90,91 por cento) dos pacientes. O exame do LCR, foi realizado em 67 (87 por cento) dos pacientes, foi anormal em 64 (95,52 por cento), tendo como achado mais frequente a pleocitose. Näo houve diferença significativa no comportamento do LCR nas diversas formas clínicas neurológicas observadas, nem quando comparadas as formas ictéricas com as näo ictéricas. Bastante significativos foram os resultados da reaçäo de microaglutinaçäo para leptospirose no LCR

ABSTRACT

Entre 1-janeiro e 30-setembro-1990 foram estudados 77 pacientes com diagnóstico de leptospirose: 64 (83,11 por cento) eram do sexo masculino e a média de idade, 28 anos. Os sorovars icterohemorrhagiae e canicola foram os mais frequentes. O exame do LCR, realizado em 67 (87,0 por cento) dos pacientes, foi anormal em 64 (95,52//). A reaçäo de microaglutinaçäo para leptospirose com antígenos vivos foi realizada no LCR, bem como reaçöes imunológicas para sífilis, cisticercose e esquistossomose para diagnóstico diferencial. Bastante signficativa foram os resultados da reaçäo de microaglutinaçäo para leptospirose no LCR, pela semelhança das respostas àquelas encontradas no sangue quanto à identificaçäo do sorovar
