Neck pain with C6 inflammation, right arm pain, 1 year follow up eval for changes. There are multiple unchanged vertebral segmentation anomalies, including congenital fusion of C3 through C6 with a "wasp-waist" morphology and a dysmorphic dens. There are also postoperative findings at C1-2 posterior fusion with cerclage wire and screws. There is an apparent punctate focus of high T2 signal in the spinal cord at the C2 level with associated mild volume loss. The cervical vertebral column alignment is unchanged. There is a mild posterior disc-osteophyte complex and ligamentous hypertrophy at the level of C6-C7 that results in mild spinal canal narrowing and moderate right neural foramen narrowing. There is also a mild posterior disc-osteophyte complex at C2-3 with mild right spinal canal and moderate right neural stenosis. There is a partially-imaged cystic space superior to the cerebellar vermis, which appears flattened.
1. Unchanged postoperative findings at C1-2 and multilevel vertebral segmentation anomalies.2. A posterior disc-osteophyte complex and ligamentous hypertrophy at the level of C6-C7 results in mild spinal canal narrowing and moderate right neural foramen narrowing.3. A posterior disc-osteophyte complex at C2-3 results in mild right spinal canal and moderate right neural stenosis.4. A partially-imaged cystic space superior to the cerebellar vermis may represent an arachnoid cyst. A brain MRI may be useful for further evaluation.
