 There are post-surgical findings related to Chiari decompression. There remains a residual extradural CSF intensity fluid collection that tracks less inferiorly than previous exam, but measures up to 5 mm in thickness and is partly septated. The inferior cerebellum displays an unchanged configuration. There still appears to be narrow biphasic cerebrospinal fluid flow anteriorly across the neo-foramen magnum, but somewhat blunted cerebrospinal fluid flow posteriorly. The vertebral body heights and alignment are unchanged. There is no evidence of syringohydromyelia. The bone marrow signal is unremarkable. There is a posterior disc-osteophyte complex at C5-6 and ligamentum flavum thickening that results in spinal canal stenosis, which appears to have progressed from previous exam. However, there is no definite abnormal signal within the spinal cord parenchyma.
1.Post-surgical findings related to related to Chiari decompression with a small residual pseudomeningocele. 2.No evidence of cervical syringohydromyelia.3.Increase in the degree of spinal canal stenosis at the C5-6 level related to a disc-osteophyte complex and ligamentum flavum thickening without definite associated spinal cord signal abnormality. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
