DEVELOPMENTAL DEFECTS OF THE CISTERNA MAGNA AND DURA MATER

Abstract

In the original description, the cisterna magna cerebello- medullaris includes that part of the subarachnoid space anterior and lateral to the medulla. However, it facilitates description, and is common usage, to apply the term cisterna magna only to that part behind the medulla. The anterior part may well be called the medullary cistern. 39
