This is my MRIradiology
report following my scan on December 3, 2006. I had this scan
due
to a loss of sensation in both palms of my hands. The spine
was
done because due to the problem being symetrical he thought it was a
definately a spinal lesion around C6-7.

MRI
of the Brain with Contrast
PATIENT:
SMITH, ERIK
DATE:
12/4/06
MRI
OF THE BRAIN WITHOUT AND WITH CONTRAST
TECHNIQUE:
Sagittal T1. Axial FLAIR. Axial T2. Diffusion weighted. Axial T1.
Postcontrast axial T1.
COMPARISON:
5-5-2005.
FINDINGS:
Diffusion-weighted imaging is negative for acute infarction.
As noted previously, there are numerous foci of increased
T2/FLAIR
signal in the cerebral white matter bilaterally. Several new lesions
have developed since the prior study. In addition, there has also been
progression of prior disease.
At the junction between the corona radiata and centrum
semiovale (image
49, series 4), several additional lesions are now present as compared
with the prior study of 5/5/05. Slightly further inferiorly, on image
50, series 4, several additional lesions are also seen in the
peritrigonal regions and corona radiata both on the right and on the
left. Similarly, more lesions are seen still further inferiorly on
image 51.
On image 52 and 53, there are several more lesions now
apparent around the right ventricular trigone and occipital horn.
A new lesion is now seen to involve the right medullary
pyramid and
olive (image 59, and 60, series 4). Maximum dimension of this new
lesion is approximately 6 mm.
No definite pathologic enhancement is seen after contrast
administration (allowing for phase-encoding artifact on several
images). However, clearly the lesions are new since the prior
examination.
There is no midline shift or hydrocephalus. There is no
recent infarct or hemorrhage.
The mastoid and middle ear cavities are normal. The paranasal
sinuses are unimpressive.
IMPRESSION:
- Interval progression of disease since the prior
study of 5/5/05.
Several new lesions have emerged since the prior examination as
discussed above. These are particularly prominent with respect to the
levels of the corona radiata, corona radiata/centrum semiovale
junction, right peritrigonal region, and right medullary pyramid and
olive.
- No obvious pathologic enhancement is
present on the current examination.
- There is no
midline shift or hydrocephalus.
MRI
of the Cervical Spine with and Without Contrast
PATIENT:
SMITH, ERIK
DATE:
12/4/06
MRI
OF THE CERVICAL SPINE WITHOUT AND WITH CONTRAST:
TECHNIQUE:
Sagittal T1. Sagittal T2. Sagittal STIR. Postcontrast sagittal T1.
Postcontrast axial T1. Axial T2-weighted gradient-echo, both 3D and 2D.
COMPARISON:
No prior studies available for comparison at the time of dictation.
[They should have sent the images from my 5/16/2003
scan]
FINDINGS:
Several foci of abnormal cord signal are identified
compatible
with plaques of demyelination. Note that no axial T2 fast spin echo
sequence is available for assessment. It is recommended that the
patient be requested to return to the Department for this sequence to
provide a more comprehensive assessment of the cervical cord parenchyma
(the sagittal STIR sequence is degraded by artifact and the
gradient-echo axials are not considered optimal for cord parenchyma
evaluation).
At the level of C2, a well-circumscribed plaque is identified
(image
199 and image 270). This measures approximately 12 mm craniocaudal x 4
mm anteroposterior x 5.3 mm transverse. Slightly more cephalad, there
appears to be a possible second lesion present at the C1-2 level (image
270 and image 199). This is a small lesion measuring approximately 6 mm
craniocaudal x 2 mm anteroposterior. This second slightly higher focus
is not covered on the axial sequences.
No definite lesion is identified at the level of C3.
At the level of C4, a possible lesion is present. This is not
clearly
identified on the sagittal T2 sequence, however, it is suggested on the
sagittal STIR sequence. Also on the gradient-echo lesions, a lesion
does appear to be present here in the midline and to the right of
midline.
At the level of C5, no definite lesion is identified. The
apparent
lesion here on the STIR sequence may be artifactual. There does appear
to be some artifact overlying the gradient-echo axials as well, These
two levels could be clarified to much greater advantage by means of an
axial T2-weighted fast spin echo sequence.
At the level of C6, no definite lesion is identified and the
apparent
lesion seen on the STIR sequence is felt to be most likely artifactual.
Note that that there is a fairly prominent protrusion at the C6-7 level
which will be discussed further below.
At the level of C7, no definite cord lesion is identified.
The central canal at C6-7 is moderately stenotic at
approximately 7.3
mm. This is due to a brood-based bulge of approximately 3 mm which is
accentuated in the left paramedian region. The central canal elsewhere
appears adequate. The foramina appear adequate throughout.
There is no loss of vertebral body height or alignment. There
is no
edema in the vertebral: bodies, posterior elements or paravertebral
soft tissues.
IMPRESSION:
- Several foci of definite and possible increased
T2/STIR signal in
the cord parenchyma as discussed above. Please refer to discussion of
individual details as outlined above. Note that some of the lesions are
questionable, seen on certain sequences but not on others. Also note
that there is no axial T2-weighted fast spin echo sequence which would
be very helpful in providing a much more sensitive evaluation of the
cord parenchyma. It is recommended that this sequence also be obtained
to complete the assessment.
- The above-mentioned
foci of abnormal signal are compatible with plaques of demyelination.
- There is no obvious pathologic enhancement in the cord
parenchyma after contrast administration.
- There
is no significant tonsillar ectopia. There is no compression at the
level of the foramen
- magnum.
- Moderate
central canal stenosis is present at C6-7 due to a
broad-based bulge. The central canal elsewhere is in the adequate
range. The foramina appear adequate throughout.
