Leukemia. Examination is limited to post contrast sequences which are also motion degraded. Patient did not wish to repeat these sequences. There is suggestion of enhancing ventral epidural tissue from the L4-L5 level to the S3 level.Diffuse marrow signal heterogeneity is noted which is compatible with known leukemia.
Technically very limited study with only postcontrast sequences. Earlier precontrast sequences were also severely degraded. Patient did not wish to repeat the sequences. There is prominence of the ventral epidural soft tissue from the L4-L5 to the S3 levels which may be related to venous plexus although epidural tumor is not excluded. Would recommend repeating pre as well as post contrast lumbar spine sequences, perhaps with sedation.
