Figure 6: Brain axial magnetic resonance imaging. (a) One month before orthodontic treatment showing a few bilateral cerebral plaques (white lesions); faint marginal enhancement occurs in the right centrum semi-ovale of one lesion (arrow). There are no, brain stem, cerebellar, or upper cervical cord lesions present. (b) One month after de-bonding, showing bilateral periventricular and deep white matter of variable sizes high signal intensity foci (white lesions), these are not enhanced in the postcontrast study. The largest lesion (arrow) is adjacent to the atrium of the left lateral ventricle and measures approximately 8.4 mm × 5.3 mm. Small lesions are also noted in the corpus callosum. No intracerebral hematoma or extra-axial collections are apparent. The ventricular system is of normal size and configuration for the patient's age
