Imaging of perinatal stroke.

چکیده
The main neonatal stroke syndromes discussed in this article are: arterial ischemic stroke (AIS), including perinatal AIS, and "presumed" perinatal AIS; cerebral venous thrombosis, including cortical vein and venous sinus thrombosis and germinal matrix hemorrhage/periventricular hemorrhagic infarction; and intraparenchymal hemorrhage. This review discusses general pathophysiological mechanisms and the role of imaging in these conditions.

Coarse Tremor as the Only Sign of Perinatal Hemorrhagic Stroke: A Case Report
Background: Tremor which is the most common abnormal movement in the neonatal period might be a benign condition or the result of pathologic events and is divided into two subtypes, namely fine tremor and coarse tremor. Fine tremor is usually benign and results from some metabolic disturbance, such as hypoglycemia. On the other hand, coarse tremor is an indicator of brain insult and should be r...
متن کاملPresumed perinatal ischemic stroke: A review.
The risk of stroke is actually highest during the perinatal period. However, some newborn infants may have no signs indicative of the need of brain imaging, or brain images taken may not be sensitive enough to diagnose ischemic injuries; so, the diagnosis of stroke may be delayed several months or years. The neurological picture in patients with perinatal stroke detected through neuroimaging mo...
متن کاملArterial Spin Labeling Perfusion Magnetic Resonance Imaging Performed in Acute Perinatal Stroke Reveals Hyperperfusion Associated With Ischemic Injury.
BACKGROUND AND PURPOSE Perfusion-weighted imaging in adults with acute stroke often reveals hypoperfusion in the ischemic core and in a surrounding area of nondiffusion-restricted penumbral tissue. Perinatal stroke is common, but the perfusion pattern is rarely documented. We aimed to describe the perfusion pattern in newborns with perinatal stroke. METHODS Neonates with clinical features of ...

Plasticity of language function after brain damage can depend on maturation of the brain. Children with left-hemisphere perinatal (n = 7) or childhood stroke (n = 5) and 12 controls were investigated using functional magnetic resonance imaging. The verb generation and the sentence comprehension tasks were employed to activate the expressive and receptive language areas, respectively. Weighted l...
