title: Wernicke-like encephalopathy after autologous bone marrow transplantation.
abstract: A 15-year-old boy with non-T ALL in early 2nd remission was autografted using a regimen with busulphan 4 mg/kg/day, po, from day -9 to -6, and cyclophosphamide 50 mg/kg/day, iv, from day -5 to -2. During busulphan administration he experienced a few generalized seizures, and starting on day 25 post ABMT he developed a progressively severe neurological symptomatology characterized by nystagmus, right VIth cranial nerve palsy, truncal ataxia and, finally, confusion and coma. MRI showed lesions in the periaqueductal gray matter, thalamus, mammillary bodies and putamen. Within 24 hours of treatment with thiamine he improved dramatically, but during the following weeks permanent neurologic damage with memory deficit, truncal ataxia and nystagmus became evident. To our knowledge this is the first case of Wernicke's encephalopathy reported after BMT. We suspect in this case a contribution of busulphan to the development of the syndrome.
