We describe a rare complication of myelography. A subarachnoid filling defect was apparent on the postmyelographic CT but not on conventional myelography. MR imaging performed later showed a spinal subarachnoid hematoma (SSAH), extending from L3 to L5. Lumbar puncture may rarely be a cause for SSAH and is more common in patients with coagulopathy. Significant back pain, paresis, radiculopathy, and even altered consciousness or meningeal signs may herald an SSAH.
我们描述了一种脊髓造影罕见的并发症。脊髓造影后CT显示蛛网膜下腔充盈缺损,而传统脊髓造影未见此表现。随后进行的磁共振成像显示从L3至L5的脊髓蛛网膜下腔血肿(SSAH)。腰椎穿刺很少会导致SSAH,在凝血功能障碍患者中更常见。严重背痛、轻瘫、神经根病,甚至意识改变或脑膜刺激征可能预示着SSAH。
