✅Possible Causes of T2 Hyperintensity in the L1-2 Disc:
- Reactive Edema & Inflammation – Increased water content due to endplate trauma.
- Mechanical Stress & Microtears – Micro-injuries within the disc leading to fluid accumulation.
- Endplate Damage & Nutrient Disruption – Impaired disc nutrition alters hydration.
- Hematoma Formation (Acute Stage) – Possible hemorrhagic component in the disc.
- Adjacent Bone Marrow Edema Effect – Inflammatory diffusion from the fractured vertebra.
✅Key Differentiation Points:
- Traumatic vs. Degenerative: Unlike degenerative changes, traumatic disc edema is focal, acute, and adjacent to the fracture.
- Infectious vs. Traumatic: No significant enhancement or disc space narrowing suggests trauma over infection.
- Neoplastic vs. Traumatic: No mass effect, preserved disc morphology, and isolated findings favor trauma over neoplasm.
