Purpose

To illustrate the imaging appearance of spinal meningeal cysts.

Methods & Materials

Myelography, CT myelography, magnetic resonance imaging (including CSF cine phase contrast flow imaging), and direct puncture cystography were employed to evaluate spinal meningeal cysts.

Results

The imaging appearance of all three types of spinal meningeal cysts are illustrated. Utility of direct puncture methods in some cases will also be demonstrated.

Conclusion

The three types of spinal meningeal cysts can be distinguished by noninvasive imaging. In some patients, guided cyst puncture may be prognostically useful in evaluating the drainage pattern of the cyst and in predicting the response to surgical decompression.
