Acute infarction involving the putamen, head and body of caudate nucleus as well as the posterior limb of internal capsule (territory of lateral lenticulostriate artery). It displays bright signal in DWI and low signal in ADC confirming the diffusion restriction status. Together with faintly bright signal in T2 and FLAIR without significant mass effect or  hemorrhage. MRA reveals complete occlusion of the right ICA with refilling of the ACA and MCA through circle of Willis.

Case Discussion

The basal ganglia receives its blood supply from the medial and lateral lenticulostriate arteries. While the former is branch from the ACA that supplys the anteromedial head of caudate and anterior limb of internal capsule, the latter is a branch from the MCA and supplies the putamen, head of caudate and posterior limb of internal capsule. The thalamus receives its supply from the superior cerebellar artery a branch from the basilar artery. The patient is known to have SLE.
