Female, 41 years old, with left ptosis and diplopia, progressive right-sided weakness, and sensory symptoms over three months. New bladder incontinence. Please note that only postcontrast sequences were obtained at the request of the ordering service.Scattered small lesions are redemonstrated including within the periventricular white matter, the left genu of the corpus callosum and at the left pontomedullary junction. None of these lesions demonstrates pathologic enhancement. In fact, no abnormal enhancing lesions are identified intracranially.
No pathologic enhancement is seen to correlate with multiple lesions identified on the prior MRI. Although the lack of enhancement does not provide for a more specific differential diagnosis, it does suggest that these lesions are not actively inflamed.
