Multiple sclerosis [G35], Reason for Study: ^Reason: eval for new MS lesions History: fever, abd pain, chest pain There is no evidence of acute ischemic or hemorrhagic lesion on the scan.There are several FLAIR high signal intensity lesions on bilateral periventricular white matter and suspicious on the right medial thalamus without evidence of surrounding edema. These lesions can suggest possible demyelinating disease such as multiple sclerosis, however, could also be non specific.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, or restricted diffusion/acute ischemia. 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.
Mainly periventricular white matter FLAIR high signal intensity lesions as described above. Differential diagnosis include demyelinating disease such as multiple sclerosis, however, the MR findings are non specific.
