Document Summary
Multiple sclerosis: an axial flair image showing multiple ovoid periventricular lesions, on this imaging sequence they have bright white appearance =hyper- intense. Axial flair images with juxtacortical (left) and brainstem (right) lesions. Sagittal t2 (left) and proton density (right) images showing lesions in corpus callosum. Sagittal t2 image of the cervical and upper thoracic spinal cord showing a single lesion at t2-t3. Important : it"s not always ms: not all white matter lesions are caused by ms, the next two slides show examples of lesions that were not caused by ms. Axial t2 images in patient w/migraine showing small, round lesions in deep white matter (not periventricular, not juxtacortical). Axial flair images in patient w/ migraine showing small, round lesions in deep white matter (not periventricular, not juxtacortical). Some people call these ubos (unidentified bright objects). Differential diagnosis presents like ms, i. e in patient like ms patient: young healthy, dissemination in space and time with mri typical for ms.
