The patient had neurologic and hematologic signs of vitamin B(12) deficiency, with elevated methylmalonic acid and homocysteine levels. Brain magnetic resonance imaging showed signal abnormality in the globi pallidi, as can be seen in inherited methylmalonic acidemia.The clinical and radiographic findings reversed with vitamin B(12) administration.
