A schwannoma look-alike: solitary fibrous tumor of the cauda equina. Illustrative case

Spinal SFT should be regarded as a potentially aggressive neoplasm characterized by an invasive propensity toward adjacent structures as well as distal metastases. The adoption of conservative management for ambiguous lesions may increase the risk of an adverse outcome. Therefore, in the context of uncertain spinal lesions with inconclusive MRI findings, it may be advisable to proceed with GTR in conjunction with confirmation of the definitive pathological diagnosis. https://thejns.org/doi/10.3171/CASE2585.
