History of neuroblastoma of lumbar spine, relapse x 2 s/p chemo, transplant: weight loss, fatigue, sweats. Extreme worsening back pain, and numbness of left foot (baseline). There are postoperative findings related to laminectomies from T11-T12 to L4-L5. There is a redemonstration of an enhancing extradural mass in the right aspect of the canal from L2 to L4 with scalloping of the posterior vertebral bodies and extension through the right L2-L3 and L3-L4 neural foramina with associated compression of the respective nerve roots. The mass measures up to approximately 6 cm in length and 3 cm in width and results in moderate spinal canal stenosis. The imaged portions of the spinal cord are unremarkable. The vertebral body heights are mildly reduced at L2 through L4. There is kyphotic deformity of the lumbar spine centered at L2. There is atrophy of the right psoas muscle. There are bilateral renal cysts.
1. Postoperative findings related to laminectomies from T11-T12 to L4-L5 and redemonstration of residual neuroblastoma in the right aspect of the canal from L2 to L4 with extension through the right L2-L3 and L3-L4 neural foramina and moderate spinal canal narrowing. 2. Kyphotic deformity of the lumbar spine centered at L2 may be related to insufficient biomechanical support related to surgical anatomic alterations..
