[A case of small cell lung cancer with intramedullary spinal cord metastasis].

An 83-year-old man was admitted with paraplegia and loss of all sensation below the level of umbilicus, with bowel and bladder dysfunction. Stage IV small cell lung cancer had been diagnosed two years ago and had received several courses of chemotherapies. A magnetic resonance imaging revealed an enhanced mass in the intramedullary spinal cord at the level of Th10-L1. Metastatic spinal tumor was diagnosed by clinical and radiological examinations. This is a rare case of small cell lung cancer with intramedullary spinal cord metastasis which caused various neurological symptoms.
