腹侧蛛网膜下腔的宽度通常是均匀的，除了在腰椎肿胀处逐渐变窄，在腹侧有轻微弯曲。由于脊髓倾向于靠近膜囊的背壁，特别是在胸下部区域，因此蛛网膜下腔背侧的轮廓不太明显。这种排列的解剖学背景在之前的一篇文章中描述过（R O T H 1965），主要是由发育因素解释的。脊柱后凸症的脊髓可能位于囊腹侧壁的最大凸面上，因此腹侧蛛网膜下腔相应地显得更窄。在几个表现为下背脊柱节段病变的临床症状的病例中，脊髓造影表明可以排除肿瘤的存在。主要表现为缓慢进行性痉挛性截瘫，D8 ~ D12以下感觉减退，膀胱功能紊乱。化验结果大多呈阴性。(临床结果将于1963年6月27日重新提交发表。
The ventral subarachnoid space is normally uniform in width except for a gradual narrowing at the level of the lumbar intumescence which is curved slightly ventrally. The dorsal subarachnoid space is much less distinctly outlined since the cord tends to run nearer the dorsal wall of the membranous sac, especially in the lower thoracic region. The anatomical background of this arrangement was described in a previous communication ( R O T H 1965) and was explained essentially by developmental factors. The cord in hyperkyphosis may lie nearer the ventral wall of the sac at the level of the maximum convexity so that the ventral subarachnoid space appears correspondingly narrower. Gas myelography was indicated to exclude the presence of a tumor in several cases presenting clinical signs of a lesion in the lower dorsal spinal segments. The main signs consisted in slowly progressive spastic paraparesis, hypoesthesia below the level of D8 to D12 and bladder disturbances. The laboratory findings were mostly negative. (The clinical findings will be reSubmitted for publication 27 June 1963.
