A rare cause of recurrent syncope: chemodectoma of left carotid

Abstract

Syncope is a frequent cause of access to emergency departments. Recurrent syncope may be associated with a transient lock of consciousness. When neurological or cardiological common causes of syncope are excluded, rare causes of syncope, such as solid carotid tumors, should be considered. In this study, we report a rare case of left carotid chemodectoma in a patient with frequent access to the emergency room for syncope in which a thorough differential diagnosis has been performed.
