Gas-induced spinal cord compression, also known as intraspinous pneumorrhachis, is a rare condition in which the presence of gas in the spinal canal generally does not result in any symptoms. However, in certain cases, gas can compress the spinal cord, leading to severe neurological dysfunction. This underscores the importance of early recognition and intervention. Herein, we conduct a comprehensive analysis of the literature on pneumorrhachis by searching databases such as PubMed, ClinicalKey, Web of Science, and CNKI. We discuss the etiology, pathophysiology, clinical manifestations, imaging features, differential diagnosis, treatment strategies, and prognosis of these patients. Our findings indicate that the occurrence of intraspinous pneumorrhachis is associated with various factors, including medical conditions, trauma, and infection. While most cases are limited in extent and resolve spontaneously, a subset of cases may signal a serious underlying condition.
气体性脊髓压迫症，也称为椎管内积气，是一种罕见病症，椎管内气体的存在通常不会导致任何症状。然而，在某些情况下，气体可压迫脊髓，导致严重的神经功能障碍。这凸显了早期识别和干预的重要性。在此，我们通过检索PubMed、ClinicalKey、Web of Science和中国知网等数据库，对有关椎管内积气的文献进行了全面分析。我们讨论了这些患者的病因、病理生理学、临床表现、影像学特征、鉴别诊断、治疗策略和预后。我们的研究结果表明，椎管内积气的发生与多种因素有关，包括疾病状况、创伤和感染。虽然大多数病例范围有限且可自发缓解，但一部分病例可能预示着严重的潜在疾病。
