title: Acute myelocytic leukemia relapse with intramedullary spinal cord tumor involvement during hematological remission.
abstract: A 64-year-old man who had been diagnosed as having acute myelocytic leukemia (M2 in the FAB classification) developed central nervous system involvement of intramedullary spinal cord during hematological remission. Magnetic resonance imaging showed a low signal intensity mass on T1-weighted images and a high signal intensity mass on T2-weighted images. The mass was slightly enhanced by gadolinium-diethylenetriaminepentaacetic acid. His neurological symptoms were slightly improved by intrathecal and systemic chemotherapy combined with external irradiation, although the size of the mass did not change.
