We report two cases of intraspinal extradural cysts communicating with an adjacent herniated disk that we term "disk cysts." These cysts were well defined and homogeneous, and were present in the ventrolateral extradural space adjacent to a lumbar herniated disk. They had rim enhancement on contrast-enhanced MR images, and communication with a herniated disk was revealed by diskography.
我们报告了两例与相邻椎间盘突出相通的椎管内硬膜外囊肿,我们将其称为“椎间盘囊肿”。这些囊肿边界清晰且均匀,位于腰椎间盘突出相邻的腹外侧硬膜外间隙。在增强磁共振成像上它们有边缘强化,并且通过椎间盘造影显示与椎间盘相通。
