Admission MRI supporting the diagnosis of mixed dementia of Alzheimer's disease and cerebrovascular disease. a Coronal FLAIR image demonstrating mild cortical and hippocampal atrophy. b Axial FLAIR image demonstrating a chronic lacunar infarct involving the left basal ganglia and posterior limb of the internal capsule and periventricular ischemic white matter changes.

On admission, an MRI scan demonstrated cortical and hippocampal atrophy (fig. 1a), a lacunar infarct in the left basal ganglia and internal capsule (fig. 1b), and ischemic white matter changes.
Orbitofrontal infarct possibly linked to vocalization behaviors. On admission to the hospital, an acute left occipital infarct was noted. Incidentally, a subacute infarct was detected in the left rectus gyrus/medial orbital frontal gyrus (arrows). a Axial FLAIR. b Axial DWI. c Axial T2 TSE. d Axial dADC. e Axial FLAIR image on follow-up MRI, 2 months after hospitalization. f Axial noncontrast CT scan performed 3 months after hospitalization.

An acute left occipital infarct was detected (fig. 2). More importantly, a subacute infarct was detected in the left rectus gyrus/medial orbital frontal gyrus (arrows in fig. 2).
