Measurements were taken in the axial plane for CSF width (CSFW), and interhemispheric width (IHW). The CPA is an inverted, triangular subarachnoid space containing cranial nerves (511) and blood vessels bathed in cerebrospinal fluid (CSF), located in the lateral aspect of the posterior fossa ().The tentorium forms the base of the triangle and the posterior temporal bone forms its lateral boundary. However, there are several genetic disorders in which enlargement of the subarachnoid spaces can be an early sign, or the feature of an associated syndrome, that may aid in Note the two leaves of the septum pellucidum and the extra CSF space between them. The intra-axial tumors are located within brain parenchyma and arise from the brain cells, while the extra-axial tumors are located outside brain parenchyma and arise from structures lining the brain or surrounding it.
