Abstract
BACKGROUND: Resection of intramedullary spinal cord tumors (IMSCTs) in pediatric patients results in a high incidence of spinal deformity (i.e., kyphoscoliosis often requiring fusion). Here, a 6-year-old male underwent a spinal fusion to correct postlaminectomy thoracic kyphosis following resection of an IMSCT. CASE DESCRIPTION: A 6-year-old male initially underwent multilevel thoracic laminectomies for resection of an IMSCT. Six months later, he presented with the onset of kyphoscoliosis. During adolescence he became increasingly paraparetic due to a thoracic kyphosis that had now progressed to 118°. He underwent a 360 decompression/fusion that included a T1-T9 laminectomy, a T5 to T11 anterior interbody arthrodesis/rib autograft, and posterolateral T2-T12 fusion/iliac crest autograft with Harrington rods placed from T5 to T12. Postoperative radiographs showed the thoracic kyphosis improved to 62°. However, 4.5 years later, X-rays showed the thoracic kyphosis newly progressed to 90° (i.e., from T3 to T12). Thirty-four years after this corrective surgery, he remained neurologically intact with only mild complaints of balance changes, and bladder/bowel urgency while radiographs confirmed continued stability. Further, the thoracic magnetic resonance imaging showed only chronic thoracic spine/cord changes. CONCLUSION: A 6-year-old child originally underwent a thoracic laminectomy for an IMSCT. As an adolescent, due to progressive postlaminectomy kyphosis, he underwent a successful secondary thoracic 360° decompression/ fusion. Notably, 34 years later, he did not require any surgical revision.
