Computed tomographic metrizamide myelography in syringohydromyelia.

|May 1, 1979
Summary
Computed tomographic metrizamide myelography (CTMM) aids in diagnosing syringohydromyelia. A collapsed spinal cord or visible cyst on CTMM indicates syringohydromyelia, simplifying diagnosis.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Syringohydromyelia is a complex spinal cord condition.
- Accurate diagnosis is crucial for effective treatment planning.
Observation:
- Computed tomographic metrizamide myelography (CTMM) was used to examine four patients with syringohydromyelia.
- Patients included those with and without a collapsing spinal cord.
Findings:
- A collapsed spinal cord or the presence of a contrast-containing cyst on CTMM allows for straightforward diagnosis.
- In cases without cord collapse, differentiating intramedullary cysts from tumors using CTMM can be challenging.
- Specific CTMM findings suggestive of syringohydromyelia include ventral cord border flattening, increased transverse diameter, and altered cord shape in the supine position.
Implications:
- CTMM is a valuable tool for diagnosing syringohydromyelia.
- Identifying specific imaging characteristics can aid in differentiating syringohydromyelia from other intramedullary lesions.
- This diagnostic approach can help guide surgical or conservative management strategies.
