MR imaging findings of neuropathologically confirmed corticobasal degeneration

Case No.	Atrophy (Dominant Cerebral Hemisphere)	White Matter Hyperintensity on FLAIR		Hyperintensity on T1WI in Bil Subthalamic Nucleus
Case No.	Atrophy (Dominant Cerebral Hemisphere)	Precentral Gyrus	Frontal Lobe	Hyperintensity on T1WI in Bil Subthalamic Nucleus
1	Rt frontal operculum and convexity	–	+	+
2	Bil frontal convexity	–	+	+
3	Lt frontoparietal	Bil	+	+
4	Rt frontoparietal	Rt	+	+

Note:—FLAIR indicates fluid-attenuated inversion recovery; T1WI = T1-weighted imaging; Bil, bilateral; –, no signal abnormality; +, obvious signal abnormality.
