Photothrombosis-induced Focal Ischemia as a Model of Spinal Cord Injury in Mice
Published on: July 16, 2015
Abstract:
Lacunar infarcts in the basal ganglia are known to cause various movement disorders, such as chorea, focal dystonia, and hemichorea-hemiballismus. We report here a case of putaminal lacunar infarction which presented with "painful tonic spasms" of the contralateral limbs. This consisted of paroxysmal brief, painful, flexor contractures of the upper, and occasionally the lower limb. These were not focal seizures but were controlled with carbamazepine, which has been used for the "painful tonic spasms" well-associated with multiple sclerosis. The putaminal infarct we describe is probably related to a lupus anticoagulant and systemic lupus erythematosus.
