Tremor and seizures associated with chronic manganese intoxication

Tremor and seizures developed in a 2-year-old girl receiving total parenteral nutrition. T1-weighted images on MRI revealed areas of hyperintensity in the basal ganglia, brainstem and cerebellum. Blood manganese was elevated. The symptoms and MRI abnormalities disappeared after withdrawal of manganese administration. The recommendation of daily parenteral manganese intake was discussed.
