FINDINGS: No Acute Vertebral Compression Or Malalignment. Marginal Tonsillar Ectopia

FINDINGS: No acute vertebral compression or malalignment.
Marginal tonsillar ectopia at the foramen magnum is stable.
No prevertebral mass or fluid collection.
Slight reversal of cervical lordosis is seen again.
The thin linear increased T2 signal from C5-6 through T1-T2 level is
redemonstrated from the syrinx formation seen previously.
No obvious new masses seen.

Axial scans: C2-C3 level: Minimal midline disc bulging is seen without
significant new central or neural foraminal stenosis.
C3-C4 level: Broad-based posterior disc osteophyte complex which
partially effaces the anterior CSF column. No new central or neural
foraminal stenosis. There is however new right uncovertebral spurring
encroaching upon the right neural foramina.
C4-C5 level: Direct cord impingement due to broad-based posterior disc
osteophyte causing significant central as well as bilateral lateral
recess stenosis is seen again. There is no new underlying intracord
signal at this level.
C5-C6 level: Broad-based right asymmetric posterior disc osteophyte
complex indenting the right anterolateral aspect of the cord as well
as encroaching upon the lateral recess is redemonstrated without
significant change. The syrinx diameter at this level has not changed.
C6-C7 level: The syrinx is stable. There is no new disc herniation or
central nor neural foraminal stenosis.
C7-T1 level: The syrinx is still visible and unchanged. No new disc
herniation or central or neural foraminal stenosis.


IMPRESSION: Stable syrinx with dilatation of the central canal as

described above since 3/6/2012 examination.
Persistent cord impingement at C4-C5 and C5-C6 levels also. This is
grossly unchanged also.
