Primary Cardiac Tumor Identified as the Cause of Seizure

A 65-year-old woman presented to the emergency department after a seizure. An unexplained bradycardia and heart murmur were detected and an emergency bedside echocardiography was performed. This revealed a mass in the left atrium. The provisional diagnosis of left atrial tumor was later confirmed by formal echocardiography and ultimately by histology. The first presentation of primary cardiac tumors can be misleading and sometimes presents with neurological manifestations. An early echocardiography can be diagnostic and could lead to early surgical intervention with better prognosis.
