MRIWith contrastPrimary: L3

Lumbar spine study

Focal posterior epidural lesion at L3

Small, well-defined oval focus in the posterior epidural space at L3, separate from the neural elements, with peripheral contrast enhancement. Favored to represent a proteinaceous or hemorrhagic degenerative lesion. Widespread degenerative disc disease and foraminal stenosis from L1 to S1.

Selected level

L3

Epidural lesion

Small, well-defined oval focus in the posterior epidural space, separate from the neural elements, with peripheral contrast enhancement. Favored proteinaceous or hemorrhagic degenerative lesion.

Primary finding: posterior epidural oval focus with peripheral enhancement.

Disc bulgeSignificant
Central canalModerate
Left neural foramenSignificant
Right neural foramenSignificant
  • L2–L3. Broad-based disc bulge. Gentle impression on the thecal sac. Severe bilateral neural foraminal narrowing.
  • L3–L4. Large disc bulge pressing on the nerve pathways. Slight narrowing of the central spinal canal. Quite narrow neural foramina on both sides.

L3 mass

Differential

Ranked as the radiologist framed them — not as probabilities.

  1. Synovial cyst

    Favored

    A fluid-filled sac arising from a degenerate facet joint. Fits a well-defined oval posterior epidural focus with a degenerative background.

  2. Sequestered disc fragment

    Possible

    A piece of herniated disc that has separated from the parent disc space and migrated into the epidural compartment.

  3. Neoplasm

    Less likely

    Considered less likely. Short-interval follow-up MRI with contrast is recommended to exclude a mass and watch the focus over time.

Next steps

Management path

Goal: ease nerve compression and pain. Escalate with symptoms, not with the image alone.

  1. 01

    Conservative care

    Physical therapy, over-the-counter pain relievers, and short-term activity modification to ease nerve irritation.

  2. 02

    Interventional management

    Epidural or facet corticosteroid injections can reduce inflammation around the compressed nerves and degenerate joints.

  3. 03

    Surgical consultation

    If weakness or leg pain worsens, or conservative care fails, decompression (for example laminectomy) or cyst resection may be discussed.
