“…In a similar case of ipsilateral hemiparesis, reported by Ago et al [17], fMRI demonstrated that gripping with the paretic left hand activated the ipsilateral left motor areas but not the right hemisphere motor areas. This activation pattern differs from that of the cases described by Song et al [16] since the involvement was of the unilateral rather than bilateral cortex. The difference in activation patterns could have been due to the use of different fMRI protocols or to interindividual variations in brain reorganization.…”

Supratentorial stroke presenting as contralateral hemiparesis is predominantly related to contralateral projection of the corticospinal tract. While most corticospinal fibers decussate at the level of the medulla, some tracts continue descending as ipsilateral ventral corticospinal fibers. In this systematic review of the literature and 2 case reports specifically seen in our institute, we describe the presence of ipsilateral hemiparesis in ischemic and hemorrhagic stroke patients. We compiled available information about the existence of uncrossed corticospinal tracts and/or the presence of bilateral operating motor cortical networks. There was an association in patients with congenital uncrossed corticospinal tracts and posterior fossa malformations. There was also a high correlation of ipsilateral hemiparesis in patients with remote infarction. A previous stroke was seen in 50% of the patients, all except for 1 case were ischemic in nature. Patients with previous infarcts do demonstrate an adaptive compensation for damaged or disconnected regions of an injured area. This emphasizes the need to consider the investigation for previous infarctions or underlying genetic structural defects by using certain imaging modality.

“…Considering the locations of recurrent infarcts in our patients, extrapyramidal tracts might be more likely to participate in reorganization after the first stroke. It is intriguing that in most of the previously reported cases as well as in our patients [17, 22] the new infarct caused deterioration of ipsilateral previous hemiparesis, but no detectable deficit, contralaterally, which might be a characteristic feature of reorganization in the contralateral side, possibly involving the extrapyramidal motor pathway whose damage would not normally cause a neurological deficit (‘silent stroke’) but become ‘eloquent’.…”

Background: The concept of neural reorganization after brain damage is already well established, and many previous studies have successfully reported the translocation of the neural activation in the motor-related cortices during motor tasks using functional imaging modalities. Several primate and human studies have suggested the formation of newly reorganized tracts in the ipsilesional or contralesional hemisphere, but the mechanism for the formation of these tracts is still largely unknown. Methods: Three acute stroke patients who presented with abrupt deterioration of their right-sided hemiparesis due to the infarcts following a recurrent stroke in the originally unaffected hemisphere were studied using magnetic resonance imaging (MRI), MR angiography and single-photon emission CT. The relationship between the neurological symptom on admission and the precise location of the new infarct was carefully investigated from the perspective of reorganization. Results: Diffusion-weighted MRI showed a new subcortical infarct in the right hemisphere contralateral to the initial stroke in all patients. These new lesions involved the thalamus, globus pallidus or corona radiata, sparing the area of the internal capsule. T₂-weighed MRI on admission showed an old infarct in the left middle cerebral artery territory, which had caused the original right-sided hemiparesis. Conclusion: It is proposed that the ‘extrapyramidal’ motor pathway in the unaffected hemisphere is associated with poststroke neural reorganization.

“…Prior neuroanatomical studies have firmly supported the notion that the primary motor cortex predominantly innervates the contralateral half of the body [3]. This was demonstrated by Dejerine [4] and Foerster [5], when stereotactic procedures performed for relief of Parkinsonism were noted to produce contralateral hemiparesis. However, as Nyberg-Hansen [6] demonstrated in his studies involving primates, cats, and adult rats, projection of pyramidal tract neurons to the ipsilateral spinal cord does exist.Humans are particularly interesting because in some individuals, as many as 30% of the corticospinal axons descend as the ipsilateral ventral corticospinal tract [3].…”
