RESUMO
A Caucasian man in his mid-50s presented to the emergency department with sudden onset right-sided weakness and dysarthria. CT angiogram demonstrated a small volume of left middle cerebral artery territory infarction after which the patient underwent successful thrombolysis. Initial ECG showed diffuse T wave inversion. He was admitted to an acute stroke ward where 72 hours of telemetry demonstrated normal sinus rhythm without arrhythmia. Transthoracic echocardiogram showed a reduced ejection fraction of 47% in the absence of any regional wall motion abnormality. An echogenic mass was noted in the apical inferior septal wall. Cardiac MRI demonstrated circumferential mid to apical endocardial thickening with characteristic appearances consistent with endomyocardial fibrosis (EMF). Furthermore, a visible hypointensity in the apex confirmed left ventricular thrombus adherent to the area of EMF. The patient was started on anticoagulation and heart failure therapy. He has recovered from the ischaemic stroke and is currently under outpatient surveillance.
