1/3. Facial myokymia associated with an isolated lesion of the facial nucleus.We report on a patient with transient facial myokymia. He had an isolated lesion of the right facial nucleus in the pontine tegmentum. Facial myokymia is a rare symptom and its pathogenesis is not known. Our case had a very localized lesion and we attempted to determine the case of the facial myokymia.- - - - - - - - - - ranking = 1keywords = nucleus (Clic here for more details about this article) |
2/3. blepharospasm hemifacial spasm and tremors possibly due to isolated caudate nucleus lesions.Isolated caudate nucleus lesions have only rarely been documented to cause focal extrapyramidal dysfunction. Two cases with possible infarcts in the head of left caudate nucleus presenting with contralateral tremors and blepharospasm with hemifacial spasm are reported. The possible mechanisms for such a presentation are discussed.- - - - - - - - - - ranking = 1.2keywords = nucleus (Clic here for more details about this article) |
3/3. reflex blepharospasm associated with bilateral basal ganglia lesion.A patient with a bilateral striatal lesion secondary to anoxia presented reflex blepharospasm associated with parkinsonism and dystonia in the limbs. The blink reflex excitability curve was enhanced and the R-2 response prolonged as in patients with essential blepharospasm. The findings in this patient support the notion that blepharospasm may be secondary to basal ganglia dysfunction through abnormal facilitation of reticular formation neurons controlling facial nucleus motoneuron excitability.- - - - - - - - - - ranking = 0.2keywords = nucleus (Clic here for more details about this article) |
