Brazil has experienced a Zika virus (ZIKV) outbreak with increased incidence of congenital malformations and neurological manifestations. We describe a case of a 26-year-old Brazilian Caucasian man infected with ZIKV and diagnosed with encephalomyelitis. Brain and spinal cord images showed hyperintense lesions on T2 and fluid-attenuated inversion recovery (FLAIR), and levels of proinflammatory cytokines in the cerebrospinal fluid showed a remarkable increase of interleukin (IL)-6 and IL-8. The observed pattern suggests immune activation during the acute phase, along with the neurological impairment, with normalization in the recovery phase. This is the first longitudinal report of ZIKV infection causing encephalomyelitis with documented immune activation.
RESUMO -Descrevemos o caso de um paciente de 45 anos de idade com cefaléia postural secundária a hipotensão liquórica espontânea, no qual a ressonância nuclear magnética do crânio revelou impregnação de contraste e espessamento meníngeo.PALAVRAS-CHAVE: hipotensão intracraniana espontânea, cefaléia postural, ressonância magnética, impregnação meningea difusa de gadolíneo. Spontaneous intracranial hypotension: case reportABSTRACT -Spontaneous intracranial hypotension is a rare syndrome associated with postural cephalalgia and low pressure of the cerebrospinal fluid. We report the case of a 45 years-old man with spontaneous intracranial hypotension with MRI diffuse meningeal enhancement.KEY WORDS: spontaneous intracranial hypotension, postural headache, magnetic resonance image, gadolinium meningeal enhancement.Hipotensão intracraniana espontânea (HIE) é síndrome caracterizada por cefaléia ortostática associada a baixa pressão liquórica e que desaparece rapidamente com o decúbito. Inicialmente descrita como aliquorréia aguda por Schaltenbrand, algumas observações foram relatadas na atual década [1][2][3] . Espessamento e hipercaptação de contraste meníngeo podem ser observados na ressonância nuclear magnética (RNM) do crânio de pacientes com tal síndrome, bem como presença de higroma subdural, hematoma subdural e herniação tonsilar ou incisural 4-11 .Descrevemos o caso de um paciente com características clínico-laboratoriais e de imagem compatíveis com HIE. RELATO DE CASOMVA, sexo masculino, 45 anos de idade, natural do Rio de Janeiro, apresenta-se com cefaléia há 12 dias, de forte intensidade, holocraniana com nítido predomínio nas regiões frontal e occipital, de caráter pulsátil, acompanhada de náuseas. Negava intolerância a sons intensos, fotofobia ou outras queixas visuais. A dor surgia poucos segundos após a adoção da posição ereta e desaparecia rapidamente ao deitar. Não havia relato de febre
