Abstract
Internal carotid artery (ICA) stenosis may lead to a wide range of clinical symptoms. We describe the case of a 66-year-old female who experienced a transient ischemic attack (TIA) with episodes of limb shaking caused by ICA stenosis. After epilepsy had been suspected and ruled out, studies of her left ICA showed extensive blockage as a result of atherosclerosis. Magnetic resonance angiography (MRA) revealed total occlusion of the left ICA and the patient was eventually medically managed due to the strong possibility of surgical complications. We reported this patient's clinical course to shed light on a rare manifestation of carotid stenosis that may be confused with other diagnoses if not closely scrutinized.
Highlights
Patients with Internal carotid artery (ICA) stenosis typically present with transient ischemic attack (TIA), stroke, or no symptoms at all depending on the degree of atherosclerosis
Patients with ICA stenosis typically present with TIA, stroke, or no symptoms at all depending on the degree of atherosclerosis
Some patients with severe carotid stenosis may experience a TIA accompanied by limb shaking, which can be confused with a seizure
Summary
Patients with ICA stenosis typically present with TIA, stroke, or no symptoms at all depending on the degree of atherosclerosis. TIA often causes focal neurologic deficits such as limb weakness, vision loss, or aphasia. Some patients with severe carotid stenosis may experience a TIA accompanied by limb shaking, which can be confused with a seizure
