60-year-old female with Chiari malformation and syrinx, please do with cSF flow study, evaluate spine for abnormalites/changes History: follow up There is mild reversal of the normal cervical lordosis. There is multilevel disc desiccation with multilevel degenerative endplate marrow signal. Vertebral body heights are intact. Cerebellar tonsils again extend 8-9 mm below the level of the foramen magnum, unchanged in extent or morphology. CSF flow demonstrates a small amount of biphasic CSF flow immediately posterior to the cerebellar tonsils.Redemonstrated is focal prominence of the central canal within the cord extending from C1-C2 to C2-C3. There is also cystic dilatation of the central canal extending from C5-C6 to T2-T3, measuring 4 x 4 mm in maximum dimension, with at least one septation, unchanged.C2-C3: No significant spinal or neuroforaminal stenosis, unchanged.C3-C4: No significant spinal or neuroforaminal stenosis, unchanged.C4-C5: Mild posterior disc osteophyte complex (with a slightly less prominent left paramedian disc component) and uncovertebral joint hypertrophy without significant spinal or neural foraminal stenosis. There are no new stenoses.C5-C6: Mild posterior disc osteophyte complex and uncovertebral joint hypertrophy. No significant spinal stenosis. Moderate bilateral neural foraminal stenosis. These findings are unchanged.C6-C7: Mild posterior disc osteophyte complex. No spinal canal stenosis. Moderate to severe bilateral neural foraminal stenosis. These findings are unchanged.C7-T1: No significant spinal or neuroforaminal stenosis, unchanged.Prominence of the palatine tonsils bilaterally. There is asymmetry of the piriform sinuses, right greater than left. These findings are unchanged.
1.Stable Chiari I malformation with cystic dilatation of the central canal, likely representing syringohydromyelia.2.Stable degenerative changes and stenoses.3.Persistent, yet stable, prominence of the palatine tonsils bilaterally as well as is asymmetry of the piriform sinuses, right greater than left.
