Female, 22 years old, with horizontal metastatic with left-sided numbness. Assess for multiple sclerosis flareup. Numerous T2 hyperintense lesions are again seen within the cerebral hemispheres and to a lesser extent in the brainstem and cerebellum. Several lesions which were previously round or oval and relatively active appearing have evolved into a more chronic morphology. However, there are multiple new lesions. Likewise, some lesions which previously enhanced no longer do so, while a number of lesions show new enhancement. The dominant, tumefactive lesion in the left centrum semiovale contains a small focus of enhancement but is otherwise unchanged. No evidence of significant generalized edema or mass effect is seen. Brain parenchymal volume is preserved. Ventricular size and morphology are stable and within normal limits.
Continued progression of disease with multiple newly developed lesions, some of which enhance.
