Background:
Complete surgical resection of a foraminal lumbar schwannoma may require an extended surgical exposure and facetectomy and thus secondary instrumentation. The minimally invasive technique through the use of tubular retractors may represent a valid surgical alternative.
Method:
We describe the resection of a foraminal lumbar schwannoma through the use of tubular retractors, along with its advantages and limitations. A limited medial facetectomy was performed and no stabilization was needed.
Conclusion:
Minimally invasive surgery is suitable for an efficient and safe resection of foraminal schwannomas and may help in avoiding stabilization when a limited facetectomy is performed.
