Encounter for examination for normal comparison and control in clinical research program [Z00.6], Reason for Study: ^Reason: 64 yo patient with gastroesophageal adenocarcinoma. Please rule out brain mets prior to starting study. History: as above No evidence of acute ischemic or hemorrhagic lesion on this scan.Scattered T2/FLAIR high signal intensity lesions on bilateral periventricular white matter is non specific but likely represent non specific small vessel ischemic lesions.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.A small retention cyst on the left maxillary sinus.
Minimal non specific small vessel ischemic disease as described above.No evidence of acute ischemic or hemorrhagic lesion.No abnormal enhancement.
