 Spine: Again seen are postoperative changes related to tumor resection with T7 and T8 laminectomies. Myelomalacia involving the cord from the T6 to T10 levels with associated cord deformity appears similar. The cord is again somewhat dorsally located within the thecal sac that some of these levels which may relate to adhesions. No new cord signal abnormality. Focal susceptibility at the T11 level dorsally is unchanged and consistent with postsurgical change. There is no new pathological enhancement. Again seen is enhancing nodule at the T8 level which is in the resection bed of resection from 9/2014 but smaller compared to prior pre-recent resection MRI from 7/21/2014. Lesion measures 8 mm in the craniocaudal dimension and 4 mm in the anteroposterior dimension. Axial images are motion degraded. The cervical, thoracic, and lumbar spine are in normal alignment. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. There is no significant disk bulge, herniation, spinal canal or foraminal stenosis.Brain: The brain parenchyma appears unremarkable. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable. There is no abnormal intracranial enhancement.
1. Postoperative changes of tumor resection in the thoracic spine with extensive myelomalacia from T6 to T10. Again seen is an enhancing nodule at the T8 level which is in the surgical bed of recent resection from 9/2014. Although some of this enhancement may be post-surgical, residual/recurrent tumor is not excluded. Finding is slightly more prominent than prior. Suggest close follow-up.2. No new area of enhancement in the thoracic cord or leptomeningeal disease in the spine.3. MRI of the brain is unremarkable without evidence of intracranial mass or abnormal parenchymal or meningeal enhancement.
