title: Acute encephalopathy following lumbar myelography with iohexol.
abstract: We report an unusual case of an acute encephalopathy following injection of iohexol for myelographic study, which was reversible after a treatment with water restriction and glucocorticoids. The pathophysiologic mechanism appears to be related with hyponatremia. We conclude that drinking of large amounts of fluids must be not recommendable in order to avoid the developing of encephalopathy.
