 The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. No intracranial hemorrhage or diffusion weighted abnormalities. The pituitary gland is normal in size. There are no extraaxial fluid collections or subdural hematomas. There is a solitary focus of white matter punctate T2 hyperintensity in the left anterior peri-insular white matter (series 6, image 15). Given the solitary nature of this lesion, it is likely of no clinical significance. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear.
No cerebellar ectopia to suggest Chiari malformation.
