Significance of Posterior fossa
The posterior fossa is a vital area located at the back of the skull, playing a significant role in various medical conditions. It is commonly associated with the development of haemangioblastomas and is often affected in Dandy-Walker malformation, leading to abnormal enlargement. Additionally, conditions in the posterior fossa can indicate the need for external ventricular drainage (EVD) insertion. This region is also notable for being the origin of the majority of atypical teratoid rhabdoid tumors (ATRT), with approximately two-thirds of cases arising from here.

The concept of Posterior fossa in scientific sources
The Posterior fossa is a crucial brain region at the back of the skull, linked to conditions like ATRT, which predominantly occurs here, and Dandy-Walker malformation, which causes abnormal enlargement in this area.

(1) This is a region at the back of the skull where haemangioblastomas commonly develop, as the text describes in the context of this medical condition.[1] (2) This is a region of the brain; conditions in this area can be a less common indication for EVD insertion, along with supratentorial ischemia or infarct.[2] (3) A region at the back of the skull where the majority of ATRT cases arise, approximately two-thirds.[3]
