Right sensory alien hand phenomenon from a left pontine hemorrhage.
BACKGROUND
Acute onset of a sensory alien hand phenomenon has been observed only from a supratentorial lesion involving the non-dominant hand, mostly from a right posterior cerebral artery infarction. A single acute vascular lesion resulting in a dominant hand sensory alien hand syndrome has not been previously documented.


METHODS
A 78-year old right-handed woman exhibited right sensory alien hand phenomenon from a left pontine hemorrhage. Disturbance of proprioceptive input and visuospatial perception are likely to play a role in manifesting the sign.


CONCLUSIONS
Dominant-hand sensory alien hand phenomenon may occur in an acute setting from a left pontine hemorrhage.
