Muscle weakness (generalized) [M62.81], Reason for Study: ^Reason: r/o demyelinating disease or structural lesion History: bilateral lower extremity weakness There is no evidence of acute ischemic or hemorrhagic lesion.There is no abnormal enhancement.On FLAIR/T2 weighted images, there are patchy high signal intensity lesions on periventricular white matter and centrum semiovale. These lesions are nonspecific, however, could represent nonspecific small vessel ischemic disease. Other white matter disease such as demyelinating disease is a possibility but less likely. Clinical correlation is indicated.The ventricles, sulci and cisterns are 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. Nonspecific bilateral periventricular and centrum semiovale FLAIR/T2 high signal intensity lesions.
