Summary
Epilepsia partialis continua (EPC) diagnosis can be challenging. Ictal single photon emission computed tomography (SPECT) may reveal focal increased signals when electroencephalography (EEG) is inconclusive for suspected EPC.
Area of Science:
- Neurology
- Neuroimaging
- Epilepsy Research
Background:
- Epilepsia partialis continua (EPC) is a rare form of status epilepticus characterized by continuous focal seizures.
- Diagnosis can be challenging, particularly when electroencephalography (EEG) findings are non-specific or absent during ictal periods.
Observation:
- Two patients with clinically suspected EPC presented with discordant diagnostic findings.
- EEG recordings did not reveal clear epileptic activity during the suspected ictal phases in either patient.
Findings:
- Ictal single photon emission computed tomography (SPECT) demonstrated focal hyperperfusion in distinct brain regions for both patients.
- These SPECT findings correlated with the clinical suspicion of EPC, despite the lack of EEG confirmation.
Implications:
- Ictal SPECT can be a valuable tool in diagnosing EPC when EEG is unrevealing.
- This neuroimaging technique may help clarify ambiguous cases and guide appropriate management for patients with suspected EPC.
