Convulsive syncope as the first clinical manifestation of carotid paraganglioma Síncope convulsivo como primera manifestación clínica de paraganglioma carotídeo

Abstract

Convulsive syncope is defined as an episode of loss of consciousness with tonic posture. It is part of the differential diagnoses of epilepsy, as a paroxysmal event with motor, clonic and / or myoclonic manifestations, without epileptiform discharges in the electroencephalogram. The crisis of syncope is part of the brain's response to hypoxic states and represents a challenge that has generated controversy about behavior and behavior to follow. We report the case of a 53-year-old man admitted to the emergency room for presenting a single syncopal episode, associated with tonic posture in the extension of upper extremities, supraversion of the gaze and sphincter relaxation. The extension studies showed a mass dependent on the left carotid in its bifurcation compatible with paraganglioma, which on palpation generated the appearance of events similar to that of admission simulating ictal semiology.
