increasing speaking difficulty and dizziness No evidence of acute ischemic or hemorrhagic lesion.There are multifocal tissue losses involving bilateral cerebellar hemispheres, especially involving left inferior cerebellar hemisphere, and inferior vermis as well as left occipital lobe especially around the calcarine sulcus and lingual gyrus.There are evidence of prior craniotomy on the left side occipital bone as well as right frontal burr hole. Right frontal subcutaneous located about 10mm sized fluid filled material is likely representing VP shunt reservoir. The VP shunt tip is located in the right lateral ventricle.  There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.
No evidence of acute ischemic or hemorrhagic lesion.Postoperative status of posterior fossa with multifocal tissue losses involving bilateral cerebellar hemispheres, inferior vermis and left occipital lobe as described above.VP shunt has placed through the right frontal burr hole with normal ventricle size.
