Abstract



RÉSUMÉ
L’hypertension intra crânienne idiopathique ou pseudo tumor cerebri est une pathologie rare chez l’enfant. Quand le diagnostic est tardif, la prise en charge des lésions avancées conséquentes grève en règle le pronostic visuel. Nous rapportons le cas d’une enfant de six ans référée pour une baisse d’acuité visuelle bilatérale associée à des céphalées et des vomissements. L’examen ophtalmologique a noté une acuité visuelle réduite à la perception lumineuse à l’œil droit et à 1/20e à l’œil gauche. Une paralysie du VI droit et un œdème papillaire bilatéral étaient également présents. Aucun processus expansif ou tumeur n’a été mis en évidence aux explorations radiologiques. L’analyse du liquide céphalorachidien et les analyses biologiques étaient sans particularités. L’enfant a été mise sous corticoïdes et inhibiteurs de l’anhydrase carbonique sans amélioration.

ABSTRACT
Intracranial hypertension or pseudo-tumor cerebri is a rare disease in children. The late diagnosis will delay the management and worsen the visual prognosis. We report the case of a 6-year-old girl referred for decreased bilateral visual acuity associated with headache and vomiting. Ophthalmologic examination noted reduced visual acuity to light perception at the right eye and 1/20th at the left eye. Paralysis of the right VI and bilateral papilloedema were also found. Medical imaging disclosed no expansive process or tumor. Analysis of cerebrospinal fluid and bleed showed no significant abnormalities. Treatment included corticosteroids and inhibitors of carbonic anhydrase, but there was no visual improvement.
