Non-convulsive status epilepticus with Takotsubo cardiomyopathy: a case report

A 61-year-old woman was admitted to our hospital for speech disturbance and mild consciousness impairment. Despite the absence of seizures or loss of consciousness, electroencephalographic abnormalities were observed, and the cerebral blood flow scintigraphy revealed an increase in cerebral blood flow in the left temporal lobe. These findings suggested a diagnosis of non-convulsive status epilepticus. On the third day, a twelve-lead electrocardiogram showed a negative T-wave in I, II, aVf, and V2-6. Moreover, a transthoracic echocardiogram revealed left ventricular apical akinesis. However, the coronary angiography showed no evidence of vascular stenotic lesions. We expect the present case report to contribute to the identification of non-convulsive status epilepticus with Takotsubo cardiomyopathy.
