Traditionally, syringomyelia has been treated with shunting of the cyst by placement of a catheter between the cyst and the subarachnoid space or pleural cavity.

Ependymal cysts are rare intracranial lesions that are found in the brain parenchyma, ventricles, and subarachnoid space.

Figure 5: Sagittal T1W image of the cervicodorsal spine shows multiple hyperintense foci in the subarachnoid space suggestive of fat deposition from dermoid rupture (arrows).
