57 years Male (DOB:5/2/1959)Reason: mets lung cancer, brain mets, s/p RT, on MET inhibitor and Erlotinb, pls c/w previous study to evaluate tx response. pls provide bi-dimensional measurement to all lesions per RECIST 1.1 History: mets lung cancerPROVIDER/ATTENDING NAME: JYOTI D PATEL JYOTI D PATEL There is evidence of left frontal craniotomy with hemosiderin deposition on the left frontal lobe with a focal tissue loss indicating postoperative status.There is no MR evidence of acute ischemic or hemorrhagic lesion. There is no abnormal enhancement.Patch bilateral periventricular white matter FLAIR/T2 high signal intensity lesions are seen, unchanged in terms of extent and configuration since prior scan.No abnormal enhancing 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 are clear. The visualized portions of the orbits are intact.Opacifications on bilateral mastoid air cells are seen, unchanged since prior scan.
1.Post left frontal craniotomy weight metastatic tumor removal status, unchanged.2.No evidence of abnormal enhancement.3.No evidence of acute ischemic or hemorrhagic lesion.
