Summary
Gas myelography and computed tomography (CT) effectively diagnose posttraumatic syringomyelia. These imaging techniques reveal spinal cord swelling and cysts, aiding in surgical planning for shunt placement.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Posttraumatic syringomyelia is a serious neurological condition.
- Accurate diagnosis is crucial for effective treatment.
Purpose of the Study:
- To evaluate the diagnostic utility of gas myelography and computed tomography (CT) for posttraumatic syringomyelia.
- To assess the effectiveness of these imaging modalities in identifying spinal cord changes and guiding surgical intervention.
Main Methods:
- Gas myelography was performed in 12 patients.
- Spinal computed tomography (CT) was used in four patients.
- Metrizamide contrast was administered intrathecally in 10 patients.
Main Results:
- Gas myelography revealed spinal cord swelling in 10 of 12 patients.
- CT demonstrated intramedullary radiolucent zones in three of four patients.
- Metrizamide opacified cysts in eight of 10 patients, and postoperative CT showed cyst collapse in one patient.
Conclusions:
- Gas myelography effectively delineates cyst extent and maximal dilatation for shunt placement.
- CT offers a less invasive method for definitive diagnosis of posttraumatic syringomyelia.
