Male, 52 years old, with history of lung cancer metastasis to the brain, status post surgery technique radiosurgery. A minimally enhancing lesion within the left inferior frontal lobe shows no significant interval change in size. On T2-weighted images, it measures 8 x 5 mm (image 16 series 801), previously 8 x 5 mm.A mildly rim-enhancing lesion within the left cerebellar hemisphere measures up to 6 mm in diameter (image 32 series 1101). This is similar to the prior examination and smaller than was seen on older examinations.Small enhancing lesions seen within the right superior parietal lobule (image 121 series 1101), along the left intraparietal sulcus (image 110 series 1101), and along the right occipital cortex (image 84 series 1101) show no significant interval change.None of the above lesions is associated with any significant parenchymal edema or mass effect. No new intracranial lesions are identified. No abnormal extra-axial fluid collections are evident. The ventricular system remains normal in size and morphology.
Multiple intracranial lesions are redemonstrated showing either stability or interval reduction in size. No new intracranial lesions are identified.
