Mar 12, 2021 — A large cisterna magna (mega cisterna magna) occasionally may be confused with an arachnoid cyst. Mega cisterna magna may represent a normal variant (intact cerebellum and vermis), but it may be associated with Dandy-Walker syndrome, either full blown or a variant in which the vermis is either completely or partially absent.How do MCM and AC cysts happen? Both are considered cystic lesions of the posterior brain. In the early development of the fetus an alteration occurs in the making of the system and spaces where the spinal fluid normally travels, and mega cisterna magna results as a consequence of the accumulation of spinal fluid in this space.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.
