Results of spinal meningioma surgery in patients with severe preoperative neurological deficits

Spinal meningiomas are usually benign, slow-growing tumours and are commonly associated with good patient outcome following surgery. However, the existence of a severe preoperative neurological deficit has been considered to be a possible predictor of poor functional outcome after surgery. We retrospectively reviewed data from 33 patients with 35 spinal meningiomas treated in our institution over the past 17 years and exhibiting severe preoperative deficits before surgery. Among them, 20 suffered from paraparesis and 13 were paraplegic. The mean follow-up duration was 70.7 months (range 12–183 months). By the 1-year follow-up, all patients had improved in comparison with their preoperative neurological status, and 60% of them had totally recovered. It can be concluded from this study, that, in the vast majority of cases, patients harbouring spinal meningioma with severe preoperative deficits can expect a good outcome.
