Síndrome de degeneración combinada de la médula espinal y radiculopatía en dos pacientes por quimioterapia intratecal con metrotrexato y citarabina. Casos clínicos

Intrathecal chemotherapy may be complicated with the development of myelopathies or toxic radiculopathies. This myeloradicular involvement, of toxic character, is unpredictable, since these patients have repeatedly received Intrathecal chemotherapy with the same drugs without apparent injury. The to...

We report two patients, an 18-year-old woman and a 16 years old male, who received systemic and intrathecal chemotherapy (methotrexate, cytarabine) for the treatment of an acute lymphoblastic leukemia and developed, in relation to this procedure, a spinal subacute combined degeneration.
