“…Furthermore, an occluded artery may not be visualized on catheter angiography of the brain, and the diagnosis might be confirmed retrospectively, only when a repeat angiogram reveals recanalization [6]. Occlusion of the artery of Percheron usually occurs due to embolization from heart, aorta or proximal cervico-cerebral arteries [7]. An extensive diagnostic work-up failed in detecting the source of cerebral embolization in our patient.…”

“…Because of the variable presence and size of the P1 segment, which gives rise to the paramedian arteries, the AOP may be an underdiagnosed variant. 23 At our institution, we identified 21 patients with AOP infarction during a 9-year period. In 2 large stroke series, the characteristic AOP infarct pattern was estimated to occur in 0.1% and 0.3% of all ischemic strokes.…”

BACKGROUND AND PURPOSE:Occlusion of the AOP results in a characteristic pattern of ischemia: bilateral paramedian thalamus with or without midbrain involvement. Although the classic imaging findings are often recognized, only a few small case series and isolated cases of AOP infarction have been reported. The purpose of this study was to characterize the complete imaging spectrum of AOP infarction on the basis of a large series of cases obtained from multiple institutions.

“…On improvement of sensorium, patient had amnesia for the event with occulomotor disturbances, vertical gaze palsy with some gait ataxia which improved with time. Altered consciousness can be explained by involvement of reticular activating system [10] and the disrupted connections between the thalamus and the anterior, orbitofrontal and medial prefrontal cortices. Vertical gaze palsy is due to disruption of the cortical input that traverses the thalamus to reach the rostral interstitial medial longitudinal fasciculus [11].…”

Acute onset Altered mental status is a common but clinically challenging emergency due to numerous possibilities with little clinical window and time to treat. The numerous causes include stroke, encephalitis, organ dysfunction, metabolic, endocrine and intoxication. Amongst the vascular causes, one rare but peculiar cause being artery of percheron infarct. Blood supply to the thalamus and brainstem have various anatomic variations. Artery of Percheron is one such variation in which a single arterial trunk arises from proximal segment of one of the posterior cerebral artery (PCA) and bifurcates to supply bilateral paramedian thalami. Occlusion of this artery, although uncommon results in characteristics pattern of symmetric infarction in bilateral medial thalami with or without mesencephalic infarction. We here describe a case of a gentleman who presented with sudden onset altered mental status and skew deviation. After improvement in sensorium characteristic vertical gaze palsy was noted with subtle confusion which recovered. MRI brain revealed characteristic Para median bithalamic infarcts with normal intracranial angiogram. Patient showed a slow and incomplete clinical recovery to conservative management.
