Self-limited epilepsy with centrotemporal spikes: a case report

Abstract

Introduction: Self-limited epilepsy with centrotemporal spikes (SLECTS) is a brief syndrome that is frequently associated with somatosensory symptoms, which have a tendency to evolve into generalized seizures, tonic -clone. In the electroencephalogram it is characterized by a pattern with high-voltage centrotemporal spikes, usually followed by slow waves that are activated during sleep and tend to spread or change from side to side. Asymmetry of hippocampus has been evidenced in brain magnetic resonance imaging (MRI) in patients with SLECTS. Case report: Male preschooler, who presented a primoseizure during sleep, characterized by tonic-clonic movements of the upper limbs and ocular retroversion and loss of consciousness lasting less than 1 minute, with subsequent relaxation of the bladder sphincter. Conclusions: SLECTS occurs in pediatric patients with onset from 3-15 years of life. Presenting as focal to generalized epileptic seizures that appear during sleep, with characteristic images in the EEG, also associating hippocampal asymmetry as a finding in imaging studies. It is a pathology that, although it has a benign course, must be diagnosed in time to avoid complications that compromise the patient's neurological functions in the future.
