Radiology Cases of Cerebellar Astrocytoma

CT of cerebellar astrocytoma
Axial CT with contrast of the brain shows a large heterogeneous cystic and solid mass encompassing the entire right cerebellar hemisphere which is compressing the slit-like fourth ventricle and shifting it to the left, resulting in obstructive hydrocephalus of the third and lateral ventricles.
