Diabetic uremic syndrome has been rarely reported in patients on maintenance dialysis for diabetic nephropathy who present subacutely with neurological symptoms and bilateral basal ganglia lesions. There are also a few reports on metformin-induced encephalopathy, which is clinically similar to diabetic uremic syndrome. Because some patients with each of these diseases also have metabolic acidosis, it is speculated that these two diseases may have the same pathology. Recently, the term "extrapyramidal syndromes of chronic kidney disease and dialysis" (EPS-CKDD), with associated diagnostic criteria, has been proposed to describe these conditions, and metformin use is considered a risk factor for developing these syndromes. We report a case of a patient on maintenance hemodialysis for diabetic nephropathy who was taking metformin and developed subacute parkinsonism and bilateral basal ganglia lesions that rapidly improved after discontinuation of metformin with continued maintenance hemodialysis. We should ascertain whether patients with EPS-CKDD are taking metformin because it may be inappropriately prescribed for end-stage renal disease. If metformin has been prescribed, it should be discontinued immediately; its discontinuation may lead to rapid symptom recovery and improved prognosis.
