The cisterna magna (or cerebellomedullaris cistern) is one of three principal openings in the subarachnoid space between the arachnoid and pia mater layers of the meninges surrounding the brain. The openings are collectively referred to as the subarachnoid cisterns.

A mega cisterna magna is essentially a brain that has filled with fluid. This is usually an issue that is part of the body's functioning after death, and relayed at the post-moterm exam. Mega cisterna magna refers to a larger than normal cisterna magna, one of the fluid filled spaces in the brain.

Mega cisterna magna refers simply to focal enlargement of the cisterna magna, the biggest of the subarachnoid cisterns, which is located posterior and inferior to cerebellum and dorsal surface of the brain stem, medulla oblongata, and superior to foramen magnum.
