sup], The percentages of corpus callosum, basal ganglia, thalamus, and dorsal brain stem involvement were significantly higher in the group affecting subcortical white matter than in the group affecting periventricular white matter, while the involvement of cerebral peduncles
showed no difference between the two groups.
Besides cerebral hemiatrophy, other probable brain parenchymal changes are hypoplasia of mesencephalon, lentiform nucleus and thalamus, diffuse cerebellar atrophy, and ipsilateral atrophy of the cerebral peduncle
Using animal models of TBI, our study investigated the prolonged pathological outcomes of TBI in different parts of the brain, such as the dorsal striatum, thalamus, corpus callosum white matter, hippocampus and cerebral peduncle
," Borlongan, the study's lead author, said.
Examples include complete 3rd nerve palsy accompanied by contralateral limb ataxia and tremor from involvement of the red nucleus (Claude syndrome) or by contralateral hemiparesis from involvement of descending motor (eg cortico-spinal) axons in the cerebral peduncle
(Weber syndrome) or in combination with both types of motor disorder affecting the opposite limb(s) (Benedict syndrome).
One could also identify the upper part of the cerebral peduncle
Mild atrophy was seen in ipsilateral cerebral peduncle
, thalamus, and contralateral cerebellar hemisphere.
Findings indicated a "Tl hypointense and T2 hyperintense oval to square lesion involving the lateral aspect of the right cerebral peduncle
measuring 5x6 mm in size.
If the penetrating branches are occluded, the thalamus, cerebral peduncle
, and/or brainstem may be involved (Hickey, 1992) (see Table 2).
