Reason: hx of lung CA, eval mets,pls compare to previous History: none The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a focus of signal loss on SWI present within the right cerebellar hemisphere measuring 12x4mmThere are small foci of encephalomalacia along the cerebellar hemispheres.Punctate T2 hyperintense lesions are identified on T2 but not FLAIR within the right pons, left thalamus and right caudate nucleus. There are several periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Incidental note is made of partial empty sella.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is no evidence for brain metastases. 2.Punctate T2 lesions within the cerebellar hemispheres, right pons, left thalamus and right caudate nucleus are likely vascular related. 3.Findings suggest old hemorrhage in the right cerebellar hemisphere.
