![A pilocytic astrocytoma with a predominantly solid mass and a minimal cyst-like component in a 14-year-old girl. a This coronal T2-weighted image shows a large, well-marginated mass, involving the vermis and both cerebellar hemispheres that effaces the fourth ventricle. b On an axial FLAIR image, the solid mass shows high signal intensity with hypointense cystic areas (arrows). c On an axial contrast-enhanced image, the mass shows inhomogeneous contrast enhancement, with nodules that exhibit intense enhancement (arrows) and other cystic areas that remain unenhanced (arrowheads).[2]](/images/e/e4/MRI_pilocytic_astrocytoma_3.jpg)

![Pilocytic astrocytoma of the left cerebellar hemisphere with a solid and cystic component severely compressing the fourth ventricle and the medulla, producing obstructive hydrocephalus. a An axial T2-weighted image shows a cystic, hyperintense mass with a less intense solid component (asterisks) compressing the fourth ventricle (arrow). b On a FLAIR image, the cystic component (c) shows low signal intensity, which is higher than that of the CSF and the solid component (s) shows high signal intensity. Note the low signal of the compressed fourth ventricle (arrow) and the peritumoral edema (e). c On this T1-weighted image, the solid components appear hypointense compared with grey matter. d The solid component shows high values on an ADC map. e Intense enhancement of solid components is depicted after the administration of a paramagnetic agent.[2] Image:MRI pilocytic astrocytoma 5.jpg](/images/7/78/MRI_pilocytic_astrocytoma_4.jpg)
