58-year-old male with simple partial seizures. No restricted diffusion to suggest acute ischemia. In the limited context of this examination, no intracranial hemorrhage is identified. There is left greater than right T2/FLAIR hyperintensity seen within the subcortical and periventricular frontal white matter that is consistent with encephalomalacia. There is ex vacuo dilation of the left lateral ventricle and expanded perivascular spaces secondary to this confluent encephalomalacia in the left frontal lobe. The T2/FLAIR hyperintensity is also visualized within the left internal capsule, left external capsule, and left thalamus. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1.Findings are compatible with encephalomalacia and gliosis in the left greater than right subcortical and periventricular white matter associated with extension into the left external capsule, left internal capsule and left thalamus. Etiology is nonspecific. Although it could be vascular related or could be related to other process resulting in encephalomalacia.
