An intra-axial well defined cystic lesion at the left temporoparietal region that strictly follows CSF in all basic sequences with free diffusion.
Features are more suggestive of an intra-axial cyst, mostly porencephalic cyst. features that suggest extra-axial location are:
- normal appearance of Sylvian fissure and nearby extra-axial space with no extrinsic mass effect upon the brain surface
- surrounding white matter and lateral ventricle wall around the inner surface of the lesion
- the outer wall looks continuous with brain surface
- it is not lined by a grey matter and is associated with a small amount of adjacent FLAIR hyperintensity
