Clinical analysis of syringomyelia resulting from spinal hemangioblastoma in a single series of 38 consecutive patients

•Patients with Middle duration of 6–12 months have a better prognosis.•The syringomyelia caused by SH were easily ignored because of its infrequency.•Improvement of spinal function grade may attribute to syringomyelia reduction.•SH accompanying syringomyelia should consider microsurgery as the first treatment.•It is a relatively large cohort of sporadic SH in a single center. Syringomyelia was predominantly caused by Chiari malformation or intramedullary ependymoma. The goal of this study was to identify factors related to clinical outcomes and spinal hemangioblastoma (SH)-induced syringomyelia formation in a single series of patients. Thirty-eight patients with SH were treated with microsurgery from January 2013 to December 2018. Clinical features and related factors were retrospectively analyzed in SH patients with and without syringomyelia. Out of the total number of SH patients, 21 presented with remarkable syringomyelia, resulting in an incidence of 55.26% (21/38).Gross total resection was achieved in 36 cases (94.73%), and subtotal resection was obtained in 2 patients (5.27%). Neurological symptoms improved in 34 patients, remained stable in 2 patients and were aggravated in 2 cases during follow-up. In addition, there was a notable difference between the location of tumors and syringomyelia (P
