SILVA, Ana M et al. Pseudotumor cerebri associated with hypovitaminosis A, B6 and D: About two cases. Arch. argent. pediatr. [online]. 2018, vol.116, n.3, pp.e445-e450. ISSN 0325-0075.

Idiopathic endocranial hypertension is infrequently associated with hypovitaminosis A and D. The case of an 8-year-old female with 24-hour blurred vision and bilateral papilledema is presented. Nuclear magnetic resonance was normal. Opening pressure of cerebrospinal fluid: 260 mm^O. She presented vitamin A and D deficiency and started replacement therapy. The second case corresponds to a 12-year-old male with fever and odynophagia of 3 days. History of glomerulonephritis and overweight. He had bipalpebral edema and papilledema. Computed tomography scan of the orbit: increase of fluid in the sheath of both optic nerves. Nuclear magnetic resonance: intrasellar arachnoidocele. Opening pressure of cerebrospinal fluid: 400 mmH2O. He presented vitamin D and B6 deficiency and started replacement treatment. The elevation of intracranial pressure triggers compensation mechanisms that, when they fail, can compromise life or cause serious neurological disabilities. Recognizing the cause for an accurate therapeutic approach is key to reduce the morbidity and mortality associated with this pathology.
