后颅窝的脑异常与脊髓空洞症之间的联系越来越为人所知。建议用“交通性脊髓空洞症”一词来描述脊髓空洞和第四脑室之间有交通的病例。试图解释这种联系通常涉及脑脊液流动和传输到该液体并通过该液体搏动的动脉脉搏波的概念。提示静脉压波动继发的压力变化，结合后颅窝和上颈髓的异常，更能令人信服地解释这些发现。提示枕大池区蛛网膜下腔的部分阻塞是脑脊液进入交通的原因，从而提供一种持续多年的间歇性膨胀力。
The association between abnormalities of the brain in the posterior fossa and syringomyelia is becoming well known. It is suggested that "communicating syringomyelia" is a convenient term to describe those cases in which there is a communication between the syrinx and the fourth ventricle. Attempts to explain this association have usually involved concepts of cerebrospinal-fluid flow and the arterial pulse waves transmitted to, and pulsating through, that fluid. It is suggested that pressure changes secondary to venous-pressure swings, taken in conjunction with the abnormalities of the posterior fossa and upper cervical cord, explain the findings more convincingly. It is suggested that partial blockage of the subarachnoid space in the region of the cisterna magna is responsible for cerebrospinal fluid being directed into the communication, thereby providing an intermittent distending force which may be active for many years.
