 There are no diffusion-weighted abnormalities to suggest acute ischemia. There is a subtle, small focus of increased T1 signal and enhancement within the cortex of the left postcentral gyrus (image 12, series 301 and image 137, series 12 one) with associated minimal increased FLAIR signal. This region appears to correlate to an area of hypoattenuation seen on a prior outside hospital CT. There is no other identifiable area of abnormal T2 signal or enhancement within the brain. 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.
Small focus of abnormal T1 & T2 signal with subtle enhancement within the cortex of the left postcentral gyrus may represent laminar necrosis secondary to a resolving subacute infarct. A follow up MRI of the brain with contrast is recommended in 6 months to evaluate for resolution.
