 There are scattered foci of T2 hyperintensity within periventricular and subcortical white matter without restricted diffusion, mass effect, susceptibility abnormality, or enhancement.There is a stable 4 x 4 mm transaxial dimension lesion (as measured on axial T2 images) within the right frontal lobe which is primarily T2 hypointense demonstrating susceptibility effect. There is no perilesional edema or associated developmental venous anomaly. Foci of susceptibility effect are also noted along the edge of the rightward tentorium as well as anterior falx which are felt to represent calcifications.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for acute intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and left mastoid air cells are clear. Note is made of post procedural changes involving lateral right temporal bone including retained fluid signal material within mastoid air cells. There is no abnormal enhancement within the brain.
