The mega cisterna magna freely communicates with the fourth ventricle and the cervical subarachnoid space (Figs 1.9 and 1.10). A mega cisterna magna, or Blake's pouch, refers to a condition in which the CSF retrocerebellar cisterns is enlarged with normal cerebellar morphology, according to Radiopaedia.
