Involuntary Movements After Anterior Cerebral Artery Territory Infarction

Involuntary movements after anterior cerebral artery territory infarction.

BACKGROUND AND PURPOSE Patients with anterior cerebral artery territory infarction presenting with involuntary movements have rarely been described in the literature. CASE DESCRIPTIONS The author reports 9 such patients: 3 with asterixis, 5 with hemiparkinsonism (tremor, rigidity, hypokinesia), and 1 with both. Asterixis developed in the acute stage in patients with minimal arm weakness, wher...

Bilateral infarction in the anterior cerebral artery vascular territory.

Bilirubin labeling of borderzone and anterior cerebral artery territory infarction.

A 50-year-old woman developed multiorgan system failure secondary to sepsis. She became obtunded during a period of hypotension, and cranial CT demonstrated diffuse borderzone infarction. Brain autopsy revealed green pigmentation in areas of infarction due to vascular leakage of bilirubin at sites of blood–brain barrier disruption, mapping the borderzone regions and bilateral posterior anterior...

"Alien hand" and loss of bimanual coordination after dominant anterior cerebral artery territory infarction.

Three patients with dominant anterior cerebral artery territory infarction demonstrated a severe disturbance of upper limb motor control with impaired bimanual coordination, the "alien hand" sign, and intermanual conflict, in addition to signs of callosal interruption and a transcortical motor aphasia. Recordings of movement-related potentials in one patient showed an attenuated Bereitschaftspo...

Carotid artery thrombosis and cerebral infarction after multiple traumas

Carotid artery thrombosis and concomitant brain infarction after blunt trauma are rare conditions. We report a 34-year-old woman with multiple traumas due to pedestrian car accident. At the time of initial visiting, she was somnolent and her Glasgow coma scale (GCS) score was 14. Initial vital signs (V/S) and brain computed tomography (CT) scan were normal. One day after admission to the emerge...
