The author describes a new computed tomographic finding associated with disk herniation--a low density in the posterior aspect of the disk, usually having a crescentic shape. This low density probably represents an area of fluid or blood accumulation within the annulus fibrosus caused by tearing of fibers in the annulus and an associated injury to the adjacent cartilage plate which opens into the spongiosa. Observation of this finding should support the diagnosis of a herniated nucleus pulposus.
作者描述了一种与椎间盘突出相关的新的计算机断层扫描发现——椎间盘后方低密度影，通常呈新月形。这种低密度影可能代表纤维环内由于纤维撕裂以及相邻软骨终板损伤并通向松质骨而导致的液体或血液积聚区域。观察到这一发现应有助于支持髓核突出的诊断。
