Abstract

The presence of gas in the spinal canal or pneumorachis is a rare imaging finding, typically incidental. Pneumorachis may be due to several degenerative, traumatic, infectious, tumoral or iatrogenic etiologies. We report three cases of pneumorachis in patients with lumbar back pain. A case occurred in a patient with advanced degenerative disk disease. Another was in a patient with posterior facet synovial cyst. The last was in a patient with locally advanced rectal carcinoma complicated by perforation. Pneumorachis was detected on MRI in two cases and on CT in all three cases.

摘要

椎管内气体或脊髓积气是一种罕见的影像学表现，通常为偶然发现。脊髓积气可能由多种退行性、创伤性、感染性、肿瘤性或医源性病因引起。我们报告了3例腰痛患者出现脊髓积气的病例。1例发生在患有晚期椎间盘退变疾病的患者中。另一例发生在患有后关节突滑膜囊肿的患者中。最后1例发生在患有局部晚期直肠癌并伴有穿孔的患者中。2例通过磁共振成像（MRI）检测到脊髓积气，所有3例均通过计算机断层扫描（CT）检测到脊髓积气。
