椎管内肿瘤包括多种肿瘤，包括血管母细胞瘤、副神经节瘤和脑膜瘤。这些肿瘤有几个共同的特征性影像学特征，如血管造影显示的高血管性肿块，MRI显示的低信号边缘和蛇形流空，以及静脉注射造影剂后的强烈增强。由于其丰富的血管，这些肿瘤代表了外科治疗的特殊挑战。最近，椎管内血管肿瘤的手术治疗受益于血管内技术的组合，用于更好地描绘这些病变，并促进术前减少体积和组织血流量。血管内栓塞已被证明是一种安全的手术，有助于切除这些肿瘤;因此，它已被提议作为其管理中的标准护理的一部分。
Intraspinal tumors comprise a large spectrum of neoplasms, including hemangioblastomas, paragangliomas, and meningiomas. These tumors have several common characteristic imaging features, such as highly vascular mass appearance in angiography, hypointense rim and serpentine flow voids in MRI, and intense enhancement after intravenous contrast administration. Due to their rich vascularity, these tumors represent a special challenge for surgical treatment. More recently, the surgical treatment of intraspinal vascular tumors has benefited from the combination of endovascular techniques used to better delineate these lesions and to promote preoperative reduction of volume and tissue blood flow. Endovascular embolization has been proven to be a safe procedure that facilitates the resection of these tumors; hence, it has been proposed as part of the standard of care in their management.
