INTRODUCTIONTakotsubo syndrome is an acute heart disease that mimics the typical features of acute coronary syndrome (ACS) [1]. Although takotsubo syndrome has an uncertain prevalence in the general population, in women with suspected ACS, the prevalence is estimated to be around 5-6% [2]. The annual incidence is very low and is approximately 0.02% [3][4].Unlike ACS, TS is reversible and the heart often heals within four to eight changes weeks. The syndrome is characterised by transient systolic and diastolic left ventricular dysfunction with wall motion abnormalities [5][6]. This condition, which was first described by Dote et al. in Japan in 1990 [3][4], usually affects postmenopausal women who have experienced some physical or psychological stress. However, it can also occur in the absence of these triggers [1][7].The prevalence of saccular aneurysms in the general population is estimated at 3.2%. Approximately 20 to 30% of cases present in the form of multiple aneurysms [8]. Intracranial aneurysms are generally diagnosed after episodes of subarachnoid haemorrhage (SAH), which causes a high rate of morbidity and mortality [9]. Rupture of an aneurysm is believed to be responsible for 0.4 to 0.6% of all aneurysm deaths, and approximately 10% of patients die before arriving at the hospital. [10]Takotsubo syndrome is generally reported to have an incidence of 0.8-17% in patients with SAH caused by ruptured aneurysm [11]. However, this case report is relevant for the clinical and pathophysiological observation of the possible association between aneurysms of the internal carotid arteries (ICA) and TS, with the latter being able to serve as an alert for possible aneurysms and thus allow for intervention prior to disruption.
