A case of acute hemiballism and neurogenic pain associated with parietal lobe infarct.

Abstract

Acute involuntary movement like hemichorea,
hemiballism and athetosis are
extremely rare after cortical infarction. A
56-year-old, right-handed, hypertensive
and diabetic man presented as acute onset
of involuntary movements of his right
arm.Neurological examination revealed,
involuntary, brisk, high-amplitude,very
fast, unpredictable movements of the
proximal segment of the left upper extremity
and mild apraxia of right
hand,else everything was normal.He also
had unbearable burning pain deep in the
right arm.Involuntary movements settled
with Haloperidol.MRI scan revealed
acute infarct in the right anterior parietal
cortex while basal ganglia structures
were normal
