Summary
Computed tomography (CT) effectively identifies spinal canal stenosis from extradural lesions. However, CT may miss neurinomas without intrathecal contrast, highlighting myelography
Area of Science:
- Radiology
- Neurosurgery
- Spinal Imaging
Background:
- Spinal canal stenosis can result from various pathologies.
- Accurate diagnosis is crucial for effective treatment planning.
Purpose of the Study:
- To evaluate the diagnostic utility of computed tomography (CT) in cases of complete myelographic stop.
- To identify the limitations of CT in diagnosing spinal canal stenosis.
Main Methods:
- Retrospective analysis of 15 cases with complete myelographic stop.
- Review of CT scans performed on these patients.
Main Results:
- CT demonstrated spinal canal stenosis in 11 out of 12 cases with extradural lesions (92%).
- Stenosis was associated with disk pathology in some cases, including one large herniated disk.
- CT failed to visualize three neurinomas without intrathecal contrast medium.
Conclusions:
- CT is highly sensitive for extradural spinal canal stenosis.
- The inability of CT to visualize certain lesions (e.g., neurinomas) without contrast necessitates myelography in specific clinical scenarios.
