[Devic's optic neuromyelitis and viral hepatitis type A. A paediatric case report].
BACKGROUND
Devic optic neuromyelitis is a rare clinical disease that involves severe transverse myelitis and unilateral or bilateral optic neuropathy. Its pathogenesis would be explained by demyelinization triggered by bacterial or viral infections phenomena. According to several author, prognosis would be better in children.


METHODS
We report a case of optic neuromyelitis in an 8-year-old child with an uneventful history who was admitted because he suffered from flaccid tetraplegia and sudden decline of the visual acuity. The ophthalmologic examination revealed bilateral neuropapillitis. The medullary MRI visualized a spreading myelitis with bifocal arachnoiditis. Search for a precipitating infectious factor showed positive IgM for viral hepatitis A. With corticosteroid treatment the child achieved total recovery of vision and recovered motor and sensorial function of the upper limbs and the trunk. Paraplegia with sphincteral disorders persisted.


CONCLUSIONS
This case characterized by the precipitating factor (hepatitis virus A), illustrates this rare syndrome. We present a general review of the pediatric cases reported in the literature.
