 There is a 25 x 19 x 28 mm peripherally enhancing lesion centered in the left anterior basal ganglia involving the caudate head, anterior limb of the internal capsule, and anterior putamen. There is mild local mass effect and mild vasogenic edema in the surrounding white matter. No additional abnormal foci of enhancement are identified. There is no significant midline shift. There is normal enhancement of the major intracranial vascular structures.
Examination limited to sequences for operative planning demonstrates a peripherally enhancing mass centered in the left anterior basal ganglia with mild surrounding edema.
