“…Besides four major thalamic arteries, branching from the PComA and P1 and P2 segment of the PCA, variations of the vascular supply of the thalamus are frequent and may explain the highly variable appearance of unilateral thalamic infarction, as well as involvement of multiple territories. In line with previous reports, infarction in the territory of the inferolateral arteries was the most common subtype followed by infarctions in the territory of the paramedian, tuberothalamic, and posterior choroidal arteries as well as infarctions involving more than one thalamic territory . In general, TOF‐MRA demonstrated an associated vascular pathology in 44.1% of patients and in 24.3% of patients, a vascular pathology was observed in the corresponding segment artery of the CoW.…”

“…Acute thalamic infarction accounts for about 11‐14% of acute ischemic stroke in the posterior circulation and has been studied in detail with regard to clinical aspects, etiologies, and magnetic resonance imaging (MRI) findings such as topographic patterns . Additionally, magnetic resonance angiography (MRA) can be used to reveal an associated vascular pathology of the basilar artery (BA), the posterior cerebral artery (PCA), and the posterior communicating artery (PComA) as well as variations in Circle of Willis (CoW) configuration.…”

“…Two readers assessed the posterior circulation Acute Stroke Prognosis Early CT Score (pc-ASPECTS) on the DWI, according to the method described by Tei et al 2 Then, readers determined the presence or absence of a thalamic infarction, and they classified thalamic infarctions into 4 categories, according to arterial territories: (1) anterior, (2) posteromedial, (3) ventrolateral, or (4) posterolateral infarction. 10 …”

Background and Purpose— Factors related to prognosis after a modern mechanical thrombectomy in patients with acute basilar artery occlusion remain unclear. This study investigated the prognostic factors for patients with acute basilar artery occlusion who underwent a stent-retriever thrombectomy. Methods— We analyzed clinical and pretreatment diffusion-weighted imaging (DWI) data in 50 consecutive patients with acute basilar artery occlusion treated with stent-retriever thrombectomy. A good outcome was defined as a modified Rankin Scale score of 0 to 2 at 3 months. The association between clinical and DWI parameters and functional outcome was evaluated with logistic regression analysis. Results— In a univariate analysis, the following variables were significantly associated with outcome: age, hypertension, baseline National Institutes of Health Stroke Scale, posterior circulation Acute Stroke Prognosis Early CT Score on a pretreatment DWI, posterior circulation Acute Stroke Prognosis Early CT Score of ≥7 (versus <7), thalamic infarction, and bilateral thalamic infarction. In a multivariate model, only a low initial National Institutes of Health Stroke Scale score (odds ratio, 0.82; 95% confidence interval, 0.709–0.949; P =0.008) and high DWI posterior circulation Acute Stroke Prognosis Early CT Score (odds ratio, 1.854; 95% confidence interval 1.012–3.397; P =0.045) were significant independent predictors of good outcome. In a univariate analysis, bilateral thalamic infarction was associated with a poor outcome (odds ratio, 1.993; 95% confidence interval, 1.187–3.346; P =0.035) but not with a unilateral thalamic infarction ( P =0.525). Conclusions— This study suggested that initial infarction severity and posterior circulation Acute Stroke Prognosis Early CT Score on a pretreatment DWI are independent predictors of clinical outcome after stent-retriever thrombectomy in patients with acute basilar artery occlusion.

“…Thalamic infarctions are commonly unilateral; bilateral thalamic infarctions occur infrequently in patients with anomalous thalamus perfusion [1]. Paramedian infarction is the second most common type of thalamic infarction, after thalamogeniculate infarction, and is characterized by several neuropsychologic, oculomotor, and consciousness disturbances.…”

Bilateral paramedian thalamic infarction is a rare subtype of stroke caused by occlusion of the artery of Percheron, an uncommon variant originating from one of the posterior cerebral arteries. This type of stroke has several major clinical presentations: altered mental status, behavioral amnestic impairment, aphasia or dysarthria, ocular movement disorders, motor deficits, cerebellar signs, and others. Few cases of bilateral paramedian thalamic infarction-related pseudobulbar palsy characterized by dysarthria, dysphagia, and facial and tongue weakness have been reported. We report here a rare case of acute severe pseudobulbar palsy as a manifestation of bilateral paramedian thalamic infarction.
