Abstract:
Radiation myelopathy (RM) is a rare complication of spinal cord irradiation. Diagnosis is based on the history of radiotherapy, laboratory tests, and magnetic resonance imaging of the spinal cord. The MRI findings may nevertheless be quite unspecific. In this paper, we describe the findings of diffusion tensor imaging in a case of the delayed form of RM. We observed areas of restricted diffusion within the spinal cord which probably corresponded to the ischemic changes. This would concur with the currently accepted pathogenetic theory concerning RM.
Insights
Radiation myelopathy (RM) is a rare spinal cord complication. Diffusion tensor imaging revealed restricted diffusion in delayed RM, supporting ischemic changes as the cause.
Area of Science:
- Neurology
- Radiology
- Oncology
Background:
- Radiation myelopathy (RM) is a rare but serious complication following spinal cord irradiation.
- Diagnosis often relies on radiotherapy history, lab tests, and conventional MRI, which can be unspecific.
Observation:
- This study details diffusion tensor imaging (DTI) findings in a patient with delayed-onset RM.
- Specific areas of restricted diffusion were identified within the spinal cord.
Findings:
- The observed restricted diffusion on DTI likely represents ischemic changes within the spinal cord.
- These findings align with the established pathogenetic theory of radiation myelopathy.
Implications:
- DTI may offer improved diagnostic capabilities for detecting early ischemic changes in radiation myelopathy.
- This technique could enhance the understanding and management of post-radiation spinal cord injury.
