Extra dural synovial cyst (MR).





PROTOCOL:       T1W & T2W - Sagittal & Axial scans


FINDINGS:

-There is normal lumbar lordotic curvature. 
-Vertebrae under view show normal MR morphology. Vertebral bodies show normal height, alignment and signal intensities.

-Lumbar spondylosis.
The intervertebral disc show abnormal hyper intense signal on T2W scans.
L4-5: Diffuse disc bulge / osteophyte complex causing mild thecal indnetation and bilateral mild to moderate foraminal encroachment.
L5-S1: Diffuse disc bulge causing mainly indnetation of both traversing nerve roots.
No other significant focal protrusion or diffuse disc bulge is noted.
-Evidence of an extra dural cyst is noted related to the right facet joint of L4-5 causing indentation of the theca; picture is suggestive of synovial cyst (9.4 mm) for clinical correlation.
-Right L5-S1 facet joint arthropathy.

-Spinal canal dimensions are adequate.
-The rest if the facet joints and ligamentum flava show normal signal intensity.
-Thecal sac, conus and cauda equina are normal in appearance.
-Paravertebral muscles show normal MR morphology and signal intensity.


IMPRESSION

·        Degenerative disc disease with disc lesion.
·        Right L4-5 synovial cyst indentating the right side of the theca and resulting in encroachment upon the right neural foramen for clinical correlation.
·        Lumbar spondylosis.
