Reason: spinal cord ganglioglioma, resection,multiple non-enhancing nodular lesions within the lateral ventricles, suprasellar cistern, and cisterna magna. History: 6 month follow up evaluation for changes, left arm weakness. MRI Brain: There are stable findings related to suboccipital craniotomy. There are several unchanged nonenhancing T2 hyperintense nodules along the septum pellucidum, lateral margin of the left ventricle, in the suprasellar cistern, and along the dura of the cisterna magna. There is no acute intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The scalp soft tissues and orbits are unchanged. Cervical Spine: There are stable findings related to suboccipital craniotomy and posterior arch of C1 resection for posterior fossa decompression and laminoplasty from C2 through T1. There is no significant interval change in the exophytic enhancing tumor along the ventral aspect of the spinal cord at the C4 through C6 levels, which measures up to 23 mm. There is volume loss of the cervical cord between the craniocervical junction and C4-5. There is also a stable syrinx in the upper cervical spinal cord that measures up to 2 mm in width. There is unchanged loss of the usual cervical lordosis. The vertebral body heights are preserved. There is no significant spinal canal stenosis. The paraspinal soft tissues are unchanged.Thoracic Spine: There is no significant change of the syrinx that extends from C7 through T5, which measuring up to 2 mm in width. The diffuse contour deformity of the spinal cord is also unchanged. There is normal alignment of the thoracic spinal column. The vertebral heights are preserved. There is no significant spinal canal stenosis. The paraspinal soft tissues are unchanged.
1.Stable enhancing mass associated with the ventral aspect of the cervical cord, as well as multiple non-enhancing nodular intracranial lesions, which may represent metastases.2.No significant change in the cervicothoracic syringohydromyelia.
