Computed tomography of a sacral perineural cyst
Journal of Computer Assisted Tomography
|May 1, 1985
Summary
Symptomatic sacral perineural cysts can be diagnosed using CT scans. These cysts may not be visible on metrizamide myelograms, but CT imaging provides strong diagnostic evidence.
Area of Science:
- Radiology
- Neurology
- Neurosurgery
Background:
- Sacral perineural cysts are rare, fluid-filled sacs that can cause neurological symptoms.
- Diagnosis often relies on imaging, but can be challenging.
Observation:
- A case of a symptomatic sacral perineural cyst is presented.
- Computed Tomography (CT) imaging was utilized for diagnosis.
- Metrizamide myelography was performed for comparison.
Findings:
- The sacral perineural cyst was clearly visualized on CT scans.
- The cyst did not enhance or fill during the metrizamide myelogram.
- CT findings were highly indicative of a sacral perineural cyst.
Implications:
- CT imaging is a valuable tool for diagnosing sacral perineural cysts.
- The limitations of myelography in visualizing these cysts are highlighted.
- Accurate diagnosis via CT can guide appropriate clinical management.
