Ischaemic stroke syndromes in the vascular territory of middle cerebral artery may have atypical presentation and radiographic findings because of the variable anatomy of that artery.

Further work-up revealed that she had a large left-sided lenticular nuclear infarction with some extension into the surrounding areas-the striatocapsular infarction.
