Malignant neoplasm of upper lobe, right bronchus or lung [C34.11], Reason for Study: ^Reason: initial lung ca staging History: initial lung ca staging No evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.Multifocal bihemispheric scattered FLAIR/T2 high signal intensity lesions on periventricular white matter and centrum semiovale indicate 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 are clear.Focal fluid collections on the right mastoid air cells are seen.
1. No evidence of intracranial metastasis.2. No evidence of acute ischemic or hemorrhagic lesion.3. Nonspecific small vessel ischemic disease.
