Abstract

Malignant peripheral nerve sheath tumors (MPNST) are uncommon aggressive neoplasms, frequently associated with type I neurofibromatosis. This is the first case of intradural lumbar spine MPNST with intraoperative findings of associated subarachnoid hemorrhage (SAH). A 72-year-old man presented to the emergency department with severe acute low back pain. Neurological examination was unremarkable. Gadolinium-enhanced MRI of the lumbar spine showed an irregularly shaped intradural lesion extending from L3 to L5. The lesion exhibited a medium signal both on T1 and T2-weighted imaging with peripheral enhancement. Through an L3-L5 laminectomy, a diffuse SAH, and a tumor tightly adherent to cauda equina nerve roots were found. Specimen examination revealed a fusocelular tumor with pleomorphic and hyperchromatic nuclei, positive for S100, and SOX10. On an 8-month follow-up, he had no neurological deficit, with a Karnofsky performance score of 90 points. Surgical evidence of SAH in lumbar spine intradural MPNST is a novel finding.

期刊介绍： Neurocirugía is the official Journal of the Spanish Society of Neurosurgery (SENEC). It is published every 2 months (6 issues per year). Neurocirugía will consider for publication, original clinical and experimental scientific works associated with neurosurgery and other related neurological sciences. All manuscripts are submitted for review by experts in the field (peer review) and are carried out anonymously (double blind). The Journal accepts works written in Spanish or English.
