In ASPECTS, subcortical structures are allotted 3 points. Which structures are included?

• A. Caudate, lentiform nucleus, internal capsule
• B. Caudate, thalamus, brainstem
• C. Putamen, globus pallidus, hippocampus
• D. Caudate, cerebellum, amygdala

Answer: (A)

ASPECTS uses a 10-region map of the MCA territory, with subcortical structures accounting for three of those points. The subcortical set includes the caudate nucleus, the lentiform nucleus (which combines putamen and globus pallidus), and the internal capsule. The thalamus, brainstem, hippocampus, cerebellum, and amygdala are not part of this subcortical trio, and insula plus the cortical regions cover the remaining seven points. Therefore, the structures included in the subcortical portion are the caudate, lentiform nucleus, and internal capsule.
