Case in brief
A 62-year-old woman experienced cognitive decline, including perseverative behavior and disorientation, following a right medial frontal acute infarction due to anterior cerebral artery occlusion. Neurological examination showed intact motor function, but she exhibited severe left-sided visuospatial neglect, confirmed by neuropsychological testing. Diffusion tensor imaging revealed significant disruption of the right cingulum bundle, indicating a unique presentation of pure visuospatial neglect without motor deficits.
What made this case unusual
This case highlights pure visuospatial neglect occurring in the context of anterior cerebral artery infarction, which is typically associated with motor deficits or motor neglect.
Diagnostic / clinical pearl
Clinicians should be aware that anterior cerebral artery infarctions can lead to pure visuospatial neglect, necessitating thorough neuropsychological assessments even when motor function appears intact.
Why it matters
Understanding this atypical presentation can improve recognition and management of cognitive deficits in patients with anterior cerebral artery infarctions, emphasizing the need for targeted rehabilitation strategies.
