Bilateral painful epileptic seizures of the hands
Insights
This report details a rare case of secondary sensory seizures (SSS) in a 14-year-old male experiencing painful hand seizures. The study highlights unique characteristics differentiating this case from other SSS patients.
Area of Science:
- Epilepsy research
- Neurology
- Clinical case studies
Background:
- Secondary sensory seizures (SSS) are exceptionally uncommon epileptic events.
- Understanding the diverse manifestations of SSS is crucial for accurate diagnosis and management.
- This case contributes to the limited literature on SSS, particularly those with sensory symptoms.
Observation:
- A 14-year-old male presented with a decade-long history of habitual, painful seizures affecting the backs of both hands.
- Consciousness impairment was infrequent during these painful episodes.
- Ictal electroencephalogram (EEG) revealed 4-6Hz rhythmic waves in the right anterior and mid-temporal regions coinciding with pain.
Findings:
- The patient's presentation included childhood onset, absence of brain tumors (confirmed by CT/MRI), and isolated sensory seizures.
- These features distinguish the case from previously reported instances of SSS.
- The specific localization of EEG abnormalities correlated with the reported sensory symptoms.
Implications:
- This case expands the clinical spectrum of secondary sensory seizures.
- It underscores the importance of detailed ictal EEG analysis in diagnosing rare seizure types.
- Further research into the neurobiological underpinnings of sensory seizures is warranted.
Abstract:
Secondary sensory seizures (SSS) are very rare epileptic seizures. A 14-year-old male patient with habitual painful seizures of the backs of both hands since the age of four is reported. The painful seizures were rarely followed by impairment of consciousness. Ictal EEG showed 4 to 6Hz rhythmic waves over the right anterior and mid-temporal area following complaints of pain. The absence of tumorous lesions on brain CT or MRI, childhood onset and the absence of combined seizures were characteristic features of this case compared with other patients reported to have SSS.
