MRI results HELP!! what does this mean

[Kalies12]

Impression

Small arachnoid cysts are present in the posterior fossa which contour the
dorsal surface of the cerebellar hemispheres.  There is a small right basal
ganglia developmental venous anomaly.  Otherwise normal MRI of the brain.  No
acute/subacute infarction, intracranial mass, or evidence of acute intracranial
hemorrhage.

Mild degenerative changes are present in the cervical spine resulting in at
most, mild spinal canal stenosis.  No significant neural foraminal narrowing.  
No intrinsic cord abnormality.
There is no abnormal enhancement demonstrated on the MRI of the brain or MRI of
the cervical spine.

Narrative
MRI OF THE BRAIN WITHOUT AND WITH IV CONTRAST
MRI OF THE CERVICAL SPINE WITHOUT AND WITH IV CONTRAST

INDICATION: Spells of decreased tenderness.  Slight twitching and tingling in
the hands.  Headaches and lightheadedness.

TECHNIQUE: Multiplanar, multisequence MRI images were performed of the brain
and cervical spine before and after the administration of intravenous contrast.


COMPARISON: None

FINDINGS:
MRI OF THE BRAIN:

The hippocampi are normal in size.  No architectural distortion is
demonstrated, nor is there abnormal signal on fluid sensitive sequences.

There is cystic signal intensity in the paramedian posterior fossa exerting
mild mass effect on the adjacent cerebellar hemisphere, consistent with an
arachnoid cysts.  There is a small developmental venous anomaly involving the
right basal ganglia.  No associated cavernous malformation is demonstrated.

Diffusion-weighted imaging demonstrates no hyperacute, acute, or early subacute
infarction.  There is no mass or mass-effect, or abnormal extra-axial fluid
collection.  

The ventricles are normal in size; no hydrocephalus.  

There are normal signal voids in the larger intracranial vessels.   The
paranasal sinuses and mastoid air cells are clear.  The marrow signal pattern
is within normal limits.

There is no abnormal brain parenchymal or leptomeningeal enhancement.

MRI OF THE CERVICAL SPINE:

There is mild straightening of the normal cervical lordosis which may be
positional.  No spondylolisthesis is demonstrated.  Vertebral bodies are normal
in height and the background marrow signal pattern is within normal limits.  No
aggressive marrow signal abnormality is demonstrated.  There is desiccation of
the C5-C6 and C6-C7 discs with mild loss of disc height.

In the superior C4 vertebral body there is a partially T1 hyperintense and T2
hyperintense lesion which loses some of its signal on T2 fat-saturated imaging
and enhances, suggestive of a partially atypical (partially lipid poor)
hemangioma, a benign entity.

The cervical spinal cord is normal in size, contour, and signal intensity.  The
craniocervical junction is normal.   The paraspinal soft tissues are normal.

Evaluation of the individual levels demonstrates:

C2-C3: Normal.

C3-C4: There is mild left uncovertebral joint hypertrophy.  No significant
spinal canal stenosis.  No significant neural foraminal narrowing.

C4-C5: Normal.

C5-C6: Broad-based dorsal disc osteophyte complex is present which partially
contours the ventral surface of the spinal cord.  There is overall mild spinal
canal stenosis.  No significant neural foraminal narrowing.

C6-C7: Broad-based dorsal disc osteophyte complex is present, slightly
eccentric to the left.  There is contouring of the ventral surface of the
spinal cord.  Overall spinal canal stenosis is mild.  No significant neural
foraminal narrowing.

C7-T1: Normal.

There is no abnormal intramedullary or leptomeningeal enhancement.
