Dysarthria due to supratentorial and infratentorial ischemic stroke: a diffusion-weighted imaging study.
Dysarthria characterized by slurring with imprecise articulation without evidence of aphasia is a frequent symptom in the acute phase of cerebral ischemia, although there is little knowledge on its anatomic specificity and spectrum of associated clinical characteristics regarding diffusion-weighted imaging (DWI). ⋯ Cortical involvement was more frequent in patients with pure dysarthria than those with dysarthria and additional neurological signs, while the frequency of pontine involvement was higher in patients with additional neurological signs than those with pure dysarthria. One third of the patients with dysarthria had multiple lesions on DWI, and the most common cause of stroke was small-artery disease. Pure dysarthria, dysarthria with lingual paresis, dysarthria with clumsy hand and dysarthria with facial paresis had predictive value for lacunar lesions.

Mechanism of infarction involving ipsilateral carotid and posterior cerebral artery territories.
We investigated the potential mechanism of infarction involving the territories of both the internal carotid artery (ICA) and the ipsilateral posterior cerebral artery (PCA). ⋯ Large artery atherosclerosis of the carotid artery was very common in patients with infarctions involving the ipsilateral ICA and PCA territories. Extracranial cervical artery evaluation is indispensable in those patients.

Subarachnoid hemorrhage as a complication of systemic lupus erythematosus.
Subarachnoid hemorrhage (SAH) is a rare complication of systemic lupus erythematosus (SLE). ⋯ SAH presents in about 1% of SLE patients. Long duration of SLE and chronic damage scores might be associated risk factors.

Stroke is regarded as a possible complication of burn. Some author reported that stroke developed in 22% of burned patients. However, the true incidence and the clinical characteristics of stroke occurring after burn injury are unknown. ⋯ Stroke is a rare complication of a burn injury in the clinical setting. It develops in moderate burns (10-50% of the total body surface area) after some time. Prevention of infection/sepsis is important to alleviate the occurrence of a stroke in these patients.
