Spinal hemangioblastomas are benign and highly vascular tumors accounting for 1-5% of intramedullary spinal tumors in surgical series. Surgery is curative in sporadic cases. We present the description of a surgical technique to safely resect an intramedullary hemangioblastoma. A dorsal midline myelotomy provides an excellent exposure of the tumor and identification of the feeding arteries. Interruption of these arteries and precise dissection of the tumor from the cord tissue followed by division of the venous drainage allow the in toto excision of the tumor. Closure of the dorsal myelotomy may be achieved with sequential fusion of the pial and arachnoid edges using a "welding" technique.

Intramedullary tumours (IMTs) are the least common neoplasms of the spinal canal. The majority of them are ependymomas and astrocytomas, the third commonest is haemangioblastoma, while other tumours of the spinal cord are relatively rare. This review presents on update on the imaging of spinal cord tumours.

Hemangioblastoma (HAB) is a benign, richly vascularized tumor that accounts for 2-6% of all spinal cord neoplasms and ranks third in the structure of intramedullary space-occupying lesions of the spinal cord. Hemangioblastoma may occur sporadically or, in approximately 30% of cases, as part of the clinical picture of a hereditary disease, von Hippel-Lindau disease. The aim of this study was to evaluate the efficacy and safety of stereotactic irradiation of hemangioblastomas of the spinal localization in patients with sporadic and von Hippel-Lindau-associated hemangioblastomas The results of stereotactic radiotherapy were evaluation of 210 spinal hemangioblastomas in 74 patients.

Background: Hemangioblastomas are highly vascularized tumors that may be associated with extensive architecture of the surrounding pathological vessels. The distinction between feeding arteries and draining veins is usually not obvious during microsurgical en-bloc tumor resection. The aim of this investigation is to provide recommendations in which hemangioblastomas intraoperative indocyanine green (ICG) videoangiography might be beneficial for safe en-bloc tumor resection.

Intramedullary primary spinal cord tumors are rare in adults and their classification has recently evolved. Their treatment most frequently relies on maximal safe surgical resection. Herein, we review, in light of the WHO 2021 classification of central nervous system tumors, the knowledge regarding the role of radiotherapy and systemic treatments in spinal ependymomas, spinal astrocytomas (pilocytic astrocytoma, diffuse astrocytoma, spinal glioblastoma IDH wildtype, diffuse midline glioma H3-K27M altered, and high-grade astrocytoma with piloid features), neuro-glial tumors (ganglioglioma and diffuse leptomeningeal glioneuronal tumor), and hemangioblastomas.

Objective: Query the National Cancer Database (NCDB) to delineate epidemiologic frequency, care patterns, and survival outcomes of pediatric intramedullary spinal cord tumors (IMSCTs).
Methods: IMSCTs included ependymoma, astrocytoma, and hemangioblastoma. We examined data from the NCDB spanning 2004-2018, focusing on IMSCT in children aged 0-21 years.
