Presumed levothyroxine-induced pseudotumor cerebri in a pediatric patient being treated for congenital hypothyroidism.

Papilledema is considered a neuro-ophthalmic emergency because of its capacity to induce irreversible end-organ damage and the often grave nature of its precipitating factor. Even more concern is warranted when papilledema presents in a pediatric setting. After excluded the contributions of intracranial masses, congenital malformations, ischemic insults and acute infections, the investigation must focus on determining the contributions of other uncharacteristic causes of pediatric pseudotumor cerebri.
