History of recurrent astrocytoma treated with chemotherapy and radiation therapy, current off therapy for 15 1/2 years. There are postoperative findings related to suboccipital craniectomy and upper cervical laminectomies. There is unchanged non-enhancing, diffuse, patchy, infiltrative T2 hyperintense signal that extends from the lower medulla to the C5 level with associated expansion of the spinal cord, particularly at the upper to mid C2 levels. There are also unchanged subcentimeter cystic cavities within the mass at the C1 and C2 levels. The vertebral column alignment is unchanged. The upper cervical vertebral bodies remain relatively small in size and there is persistent T1 hyperintense signal in the bone marrow of C2 and C3, which is likely related to radiation therapy. There is an unchanged focus od low T2 and T1 signal in the C5 vertebral body. There is no significant central spinal stenosis or neural foraminal narrowing. There is an unchanged nonspecific prominent left supraclavicular lymph node.
No evidence of cervicomedullary astrocytoma progression and stable associated treatment effects.
