title: A baby with a lot of nerve.
abstract: An infant presented with bilateral disk edema and an acute left sixth cranial nerve (CN VI) palsy because of pseudotumor cerebri (PTC). PTC is rare in infants where it is often associated with endocrine abnormalities, medications, viral infections, systemic conditions, and nutritional etiologies such as vitamin A toxicity. We report a case of PTC in an infant associated with hypervitaminosis A with an unlikely source-a common prenatal vitamin.
