 There is a subcentimeter focus of mild restricted diffusion overlying the posterior limb of the left internal capsule which has a "ring" appearance demonstrating a lack of restricted diffusion centrally. This correlates with a minimal hypointense ring on ADC with central hyperintensity. T2 imaging demonstrates this to be hyperintense, T1 is hypointense, and there is no contrast enhancement. There is also no associated susceptibility abnormality or mass effect.There are multiple foci of T2 hyperintensity throughout the periventricular and subcortical white matter without associated mass effect, restricted diffusion, susceptibility abnormality, or enhancement.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
1.Resolving, late subacute lacunar infarct overlying the posterior limb of the left internal capsule. There is no acute ischemia.2.Chronic small vessel ischemic disease.
