title: Perioptic cyst distal to optic nerve meningioma: MR demonstration.
abstract: Dilation of the subarachnoid space between the distal edge of an optic nerve sheath meningioma and the eyeball has previously been observed during surgery and considered a rare finding. We observed such perioptic cysts in seven patients with optic nerve meningioma and describe the MR features of this finding.
