56 years Male (DOB:5/2/1959)Reason: history of metastatic NSCLC to brain s/p RT History: nonePROVIDER/ATTENDING NAME: RENUKA MALIK VICTORIA M VILLAFLOR The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a moderate degree of periventricular and subcortical confluent hyperintense white matter lesions present identified on the FLAIR and T2 images. This is stable compared to the prior exam.The patient is status post left frontal craniotomy for left frontal lobe surgery.No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.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 demonstrate mild mucosal thickening. The visualized portions of the mastoid air cells are partly opacified but not significantly different compared to the prior exam. The visualized portions of the orbits are intact. The right eye lens is thin.
1.There is no evidence for local recurrence or new metastasis to the brain.2.Periventricular and subcortical white matter signal changes are nonspecific but in this case most likely treatment related.
