We report a 40-year-old man who presented with multiple bone pseudofractures after about 20 years from the onset of Wilson's disease (WD). At age 36, he first noticed pain in his left shoulder. At age 39, he had multiple chest pain. On neurologic examinations, dysarthria and dysphagia due to pseudobulbar palsy, rigidity and tremor on right upper lim were observed. WD was confirmed because of low levels of plasma cupper and ceruloplasmin in addition to ATP7B gene mutation. The chest X-ray revealed multiple fractures of the several ribs. We diagnosed osteomalacia due to Fanconi's syndrome because of hypophosphatemia and the impairment of renal tubules for WD. After administration of vitamin D, there happened no new bone pseudofractures. Although bone pseudofractures accompanied by Wilson's disease generally happen in childhood, we should be aware of this symptom even in adulthood.
