Atrial Myxoma Presenting as an Atypical Stroke in a Young Patient With a Recent COVID-19 Infection

Atrial myxomas are the most common primary tumor of the heart and can occasionally present as an ischemic stroke with neurologic symptoms secondary to embolic phenomena. We present a case of a 42-year-old male with multiple cardiovascular risk factors and coronavirus disease 2019 (COVID-19) infection two months prior who presented to the emergency department with unilateral left-sided weakness and paresthesia. After being diagnosed with multifocal ischemic strokes, further evaluation utilizing a transesophageal echocardiogram (TEE) revealed a 5 × 2 cm left atrial myxoma prolapsing the mitral valve, which was the presumed cause of the patient’s strokes. The myxoma was successfully removed via robotic thoracoscopy. Our case demonstrates the importance of considering atrial myxoma in the evaluation of stroke in young and middle-aged patients even in the presence of multiple cardiovascular and thrombotic risk factors.
