Case Reports

Bilateral caudate nucleus infarction associated with a missing A1 segment.

We describe a case of bilateral caudate nucleus infarction caused by cardioembolic stroke associated with a variant circle of Willis. The patient was an 81-year-old man with atrial fibrillation who presented with a sudden disturbance of consciousness. When he became more alert a few days later, he was abulic with no spontaneous speech or activity. ⋯ The left A1 segment was absent on 3-dimensional computed tomography angiography. One year later, abulia had completely resolved. Bilateral caudate nucleus infarction with variant circle of Willis is rare.

AbstractWe describe a case of bilateral caudate nucleus infarction caused by cardioembolic stroke associated with a variant circle of Willis. The patient was an 81-year-old man with atrial fibrillation who presented with a sudden disturbance of consciousness. When he became more alert a few days later, he was abulic with no spontaneous speech or activity. A magnetic resonance imaging scan of the brain revealed cerebral infarction of bilateral caudate nucleus heads and the left frontal lobe. The left A1 segment was absent on 3-dimensional computed tomography angiography. One year later, abulia had completely resolved. Bilateral caudate nucleus infarction with variant circle of Willis is rare.Copyright © 2012 National Stroke Association. Published by Elsevier Inc. All rights reserved.
