Unilateral stroke in a young person may be cardioembolic, and anatomical variations like a bovine aortic arch can direct emboli to a specific hemisphere.
May prompt cardiac source evaluation in young unilateral stroke; hypothesis-generating for aortic arch variants directing emboli.
A human immunodeficiency virus (HIV)-positive 29-year-old man presented with pre-syncope and acute left hemispheric infarction in multiple vascular territories. Thorax computed tomography (CT) with contrast showed bovine aortic arch and a left atrium large mass. On transthoracic echo, a 2.1 × 2.6 cm mass pointed to the heart as the embolic source. Successful surgical resection revealed cardiac myxoma. Although this presentation mimicked artery to artery embolization but having a bovine aortic arch can contribute to this stroke propensity to the left hemisphere.
