متن کاملTumefactive Multiple Sclerosis presenting as Acute Ischemic Stroke.
BACKGROUND AND PURPOSE Multiple sclerosis (MS) plaques appear as well-demarcated, homogenous small ovoid lesions on magnetic resonance imaging (MRI). Atypical radiographic features of MS lesions include size greater than 2 cm, mass effect, and edema. Tumefactive MS lesions can radiographically mimic intra-cranial neoplasms, infarction, as well as infections. In atypical cases of tumefactive dem...
متن کاملDominant perivenular enhancement of tumefactive demyelinating lesions in multiple sclerosis.
