 There is a wedge-like area of volume loss affecting the lateral aspect of the left cerebellar hemisphere. There is poorly defined mild T2 hyperintense signal in the left superior frontal lobe extending from the roof of the frontal horn of the left lateral ventricle into the subcortical white matter of the superior and middle frontal gyri, without associated mass effect or volume loss. The ventricles and sulci are within normal limits. The basal cisterns remain patent. There is no midline shift or mass effect. There are no areas of abnormal signal. There is no diffusion abnormality. No extra-axial fluid collection is identified. Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits.
1.No acute abnormality is identified.2.A small defect or area of volume loss is seen in the left cerebellar hemisphere which may be congenital or related to a previous insult, possibly ischemic.3.Vague left frontal lobe white matter signal abnormality is seen as described above of uncertain significance. The differential would include sequela of prior insult, an area of relatively delayed myelination, or less likely, a subtle cortical dysplasia.
