- Title
SELF ASSESSMENT ANSWER: An uncommon cause of lumbar radiculopathy.
- Abstract
The article presents answers to questions related to an uncommon cause of lumbar radioculopathy. Features seen on the magnetic resonance imaging scan in the case include the sagittal T2-weighted image shows low signal at L4/5 and L5-S1 levels and a high intensity cystic lesion at L4/5 level with a low signal intensity rim due to the cyst wall and facet joint hypertrophy/arthritis. Likely diagnosis of the case is that facet joint cyst can be either synovial cysts or ganglia. Synovial cysts have a synovial lining and communicate with the joint whereas ganglia, in a similar site, lack a synovial lining but otherwise have similar components.
