Malignant neoplasm of lower lobe, right bronchus or lung [C34.31] / Disseminated malignant neoplasm, unspecified [C80.0] / Dizziness and giddiness [R42], Reason for Study: ^Reason: mets lung cancer, ROS1+, on Crizotinib, c/o vertigo, concern for CNS mets. There is no evidence of acute ischemic or hemorrhagic lesion.There is no evidence of abnormal enhancement.There is focal encephalomalacia on the left parietal lobe inferior parietal lobule, in particular supra marginal gyrus indicating chronic ischemic infarct.Scattered minimal T2/flair high signal intensity lesions on periventricular white matter indicating nonspecific small vessel ischemic disease.The ventricles, sulci and cisterns are symmetric and unremarkable. 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 paranasal sinuses and mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion. No evidence of abnormal enhancement.2. Chronic ischemic infarct on the left parietal lobe inferior parietal lobule.3. Minimal nonspecific small vessel ischemic disease.
