Since tako-tsubo syndrome (TS) frequently appears soon after stroke (usually stroke involving the insular cortex), it is believed to be a consequence rather than a cause of stroke. Herein, we describe a 70-year-old woman presenting with a left middle cerebral artery stroke (involving the insular cortex) who developed a further contralateral ischemic stroke with concomitant detection of a transient intracardiac mural thrombus attributable to TS. It can reasonably be maintained that that in our patient insular stroke triggered the TS, which in turn became the embolic cause of a further stroke. Given the association between TS and the risk of embolic stroke, congestive heart failure and sudden death, stroke physicians need to promptly detect and appropriately manage this condition.
