“…[1][2][3][4][5][6][7] BGTH can be detected as either diffuse hyperechogenicity 5 or linear or fine punctuate hyperechoic foci 4,6,7 in the region of the basal ganglia and the thalamus during routine neurosonogram in neonates.…”

“…In contrast, several studies reported predominantly linear or fine punctate hyperechoic foci. [4][5][6][7] Two retrospective multivariate analyses have been conducted, one showing an association between lenticulostriate vasculopathy and high-dose magnesium sulfate, 14 and the other one showing increased odds for thalamic vessel hyperechogenicity with increasing GA, large size for date, breech presentation, and seizures. 6 Since patients with BGTH observed in our neonatal intensive care (NICU) have predominantly diffuse lesions, we sought to determine the factors associated with diffuse BGTH.…”

“…Neuropathological correlates of LSV include thickened and hypercellular blood vessel walls having intramural and perivascular mineralization, 30 as well as adventitial or subendothelial deposits of amorphous, basophilic material in small-and medium-sized arteries. 31 Of interest, LSV was first reported in the 1960s after a congenital rubella epidemic in Philadelphia. 32 Postmortem histology of the brains from affected babies showed a highly regionalized vasculitis.…”

“…Suas dimensões diminutas e sua localização distante dos canais de circulação liqüórica fazem com que eles não determinem obstrução do fluxo liqüórico, com a conseqüente hidrocefalia hipertensiva, a qual seria detectada, clinicamente, através dos sinais clássicos de hipertensão intracraniana no RN, ou no lactente. Por outro lado, a possibilidade da associação com infecções congênitas, malformações do SNC, ou com patologias neurológicas de natureza metabólica, sem manifestação clínica neonatal, é importante, pois permite que casos selecionados sejam submetidos a uma investigação mais detalhada e diagnóstico precoce.A presença de hiperecogenicidade em vasos da região dos núcleos da base e talâmicos é observada na evolução de RN pré-termo 4 , tendo sido relacionada a fenômenos de natureza anóxica 5 , infecções congênitas virais e cromossomopatias (trissomia 21 e 13) 6 . A topografia da lesão (proximidade com os gânglios da base) sugere que algumas dessas crianças possam apresentar anormalidades no desenvolvimento neuropsicomotor, envolvendo a coordenação motora fina, problemas cognitivos e do comportamento.…”
