title: Ipsilateral stroke with uncrossed pyramidal tracts and underlying right internal carotid artery stenosis treated with percutaneous transluminal angioplasty and stenting. A rare case report and review of the literature.
abstract: We present a unique case of ipsilateral stroke in a 55-year-old right-handed hypertensive man with proven uncrossed pyramidal tract demonstrated by tractography. Diffusion-weighted imaging disclosed small acute ischemic infarcts in the right corona radiata with MR angiography showing narrowing of the right internal carotid artery. Significant carotid stenosis of right internal carotid artery (ICA) was detected on digital subtraction angiography as the underlying cause and subsequently treated with percutananeous transluminal angioplasty and stenting with good outcome. The presence of uncrossed pyramidal tract was confirmed by diffusion tensor imaging tractography. To our knowledge there are few reports of ipsilateral stroke with proven uncrossed pyramidal tracts described in the literature. This is the first documented report of ipsilateral stroke with uncrossed fibre tracts due to underlying critical stenosis of the ICA treated successfully with a good recovery.
