Abstract:
This study aims to summarize the clinical features of subarachnoid hemorrhage(SAH)caused by intraspi-nal schwannoma by analyzing 19 cases of intraspinal schwannoma manifesting as SAH who were admitted to our hospital or reported in the literature.The patients in this study had the clinical manifestation of severe headache and vomiting,with-out the symptoms of spinal cord or nerve root compression.Lumbar puncture confirmed SAH,and cerebral digital subtrac-tion angiography did not show intracranial aneurysms or vascular malformations.Spinal cord MRI showed extramedullary intradural tumor in the cervical segment,and pathological biopsy results confirmed the diagnosis of schwannoma.Some cases reported in the literature not only presented with SAH but also had the symptoms of spinal cord and nerve root com-pression.The clinical features of this disease suggest that clinicians should clarify the presence or absence of the symp-toms or signs of nerve root or spinal cord compression in SAH patients with negative intracranial imaging findings and per-form reasonable examinations to exclude intraspinal lesions.Early diagnosis and complete tumor resection can not only pre-vent bleeding and recurrence,but also effectively avoid irreversible damage to the spinal cord and nerve roots caused by the compression of intradural lesions in the spinal canal,thereby helping to improve the prognosis of patients.
