Ten intramedullary and two intradural extramedullary masses of the spinal canal were evaluated with 16 separate needle aspirations. Cord fluctuance at air myelography and/or low density within the cord on computed tomography determined the level of aspiration. The condition of two patients with cystic neoplasms and one with syringohydromyelia improved after fluid removal. Endomyelography demonstrated the extent of eight intramedullary cavities. In syringohydromyelia, this information was used in determining the surgical approach. Aspiration and tissue biopsy enabled successful diagnosis of two cases of intradural extramedullary masses of unknown etiology. Needle aspiration yields valuable diagnostic information and is safe when proper guidelines are followed.
对10例髓内和2例硬脊膜内髓外椎管肿物进行了16次独立穿刺抽吸评估。空气脊髓造影时脊髓波动和/或计算机断层扫描显示脊髓内低密度区域确定了抽吸水平。2例囊性肿瘤患者和1例脊髓空洞症患者在液体抽出后病情改善。脊髓造影显示了8个髓内腔的范围。在脊髓空洞症中，这些信息用于确定手术入路。抽吸和组织活检成功诊断了2例病因不明的硬脊膜内髓外肿物。遵循适当指导原则时，穿刺抽吸可提供有价值的诊断信息且安全。
