A lumbar clear cell meningioma with foraminal extension in a renal transplant recipient.
Spinal meningiomas are characteristically dural based. We report a lumbar clear cell meningioma extending into the intervertebral foramen without dural attachment which mimics a neurilemmoma. This is a rare finding, with no other reported cases in the literature. The importance of recognizing clear cell meningioma relates specifically to its inordinately aggressive clinical course. Compared to with of spinal clear cell meningiomas reported to date, our case showing the extension into the intervertebral foramen and mimicking a neurilemmoma is rather unique. Clear cell meningioma may be confused with other clear cell tumors, especially with the similar-looking metastatic renal cell carcinoma, which should be carefully ruled out in our case - an immunosuppressed renal transplant recipient.
