Apical Ballooning Resulting from Limbic Encephalitis - 12/08/11

Abstract |
Background |
Neurogenic stunned myocardium is an increasingly recognized cause of left ventricular apical ballooning, or takotsubo cardiomyopathy. We report the first case of neurogenic stunned myocardium as a result of limbic encephalitis.
Methods |
This 73-year-old woman with anterograde and retrograde amnesia was investigated using electrocardiography, magnetic resonance imaging, and left ventricular angiography.
Results |
Electrocardiography showed deep T-wave inversions in multiple leads, magnetic resonance imaging demonstrated increased signal on fluid-attenuated inversion recovery images symmetrically within the medial temporal lobes consistent with limbic encephalitis. Left ventricular angiography showed apical ballooning.
Conclusions |
Because the insula has extensive interconnections with limbic structures, limbic encephalitis could lead to alterations in the sympathetic regulation of the insular cortex resulting in neurogenic stunned myocardium.
