Restaging of myxopapillary ependymoma. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is scattered paranasal sinus mucosal thickening.Spine: There are stable postoperative findings related to myxopapillary ependymoma resection and radiation therapy with confluent fatty bone marrow signal in the lumbosacral spine and unchanged minimally enhancing tissue in the spinal canal at the S2-S3 level. There is also degenerative endplate signal alteration affecting L1-L2 associated with an anterior disc-osteophyte complex. The spinal cord and nerve roots are unremarkable. The vertebral column alignment is unchanged. The vertebral body and disc space heights are preserved. There is no significant spinal canal stenosis. However, there is prominence of the ligamentum flavum in the thoracic spine, which results in neural foramen stenosis. There is an unchanged mass that measures up to nearly 4 cm in the region of the right adrenal gland.
1. No evidence of intracranial hemorrhage, mass, or acute infarct. 2. Unchanged post-treatment findings without evidence of tumor recurrence.3. Unchanged right adrenal regional mass. Nevertheless, dedicated imaging of this lesion may be useful.
