Reason: PCNSL, re-eval History: NHL The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.The patient is status post suboccipital craniotomy.A small focus of encephalomalacia is present in the right middle frontal gyrus. This is unchanged since the prior exam.There is encephalomalacia present along the right cerebellar hemisphere which is unchanged since prior examNormal 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 demonstrate some mild mucosal thickening.. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Small foci of encephalomalacia in the right middle frontal gyrus and right cerebellar hemisphere are redemonstrated and unchanged.2.There is no evidence for recurrent lymphoma.
