Limb Shaking Transient Ischemic Attacks with Normal Neurovascular Ultrasound may Herald Cardioembolic Stroke: A Case Report

Abstract

Our objective is to highlight that the rare occurrence of limb shaking in transient ischemic attacks may be underpinned by etiologies other than critical internal carotid stenosis/occlusion. We describe a 74 year-old woman with abrupt left arm jerking and normal urgent computed tomography scan, electroencephalography (EEG) as well as carotid and transcranial ultrasound. Two days later she developed an overt ischemic stroke, with left mesencephalon and left cerebellar hemisphere lesions at brain magnetic resonance imaging and paroxysmal atrial fibrillation at Holter-EKG. Transient ischemic attacks should be considered in the differential diagnosis of limb shaking even in patients with normal carotid and transcranial ultrasonography.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
