ABSTRACT
@#This is the report of an anterior communicating artery aneurysmal coil as the likely source of septic emboli resulting in bilateral hemispheric abscesses sparing the medial frontal, parietal and occipital lobes and brainstem. Cessation of antegrade anterior cerebral artery flow and resulting turbulent flow into the distal cortical arterial watershed of middle cerebral artery territory bilaterally is the probable mechanism for this unusual pattern.
ABSTRACT
Motor posturing in acutely comatose patient is suggestive of an evolving brain herniation. In the presence of a unilateral pupillary abnormality, a metabolic or drug induced coma can be excluded. Neuroimaging studies in such cases will likely reveal underlying mass or acute ventricular obstruction. We recently encountered a patient who presented in stupor with repetitive motor posturing and a transient right oval pupil to light stimulus. Surprisingly, an urgent brain CT revealed only mild global atrophy for age. Further evaluation disclosed cryptococcus meningitis as the underlying cause.

ABSTRACT
Clinical recognition of cerebral amyloid angiopathy is important since aggressive antiplatelet or anticoagulation use may result in intracranial hemorrhage. Following case illustrates sequential evolving sensory disturbance involving perioral and ipsilateral finger (cheiro-oral syndrome) as a manifestation of underlying cerebral amyloid angiopathy.
ABSTRACT
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. CASE REPORT: 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.
