In this case report, we present the case of a 20-month-old girl who manifested paroxysmal “bidet-induced” episodes characterized by impaired awareness, pallor, and hypotonia, with a duration of less than a minute. Initial neurological examination yielded unremarkable results, prompting further investigation. A video-electroencephalogram recording documented the epileptic nature of these episodes, revealing an ictal discharge originating from the right central-temporal region. A brain magnetic resonance imaging exhibited a sulcal/gyral asymmetry within the central sulci, along with the presence of the “power button sign” within the right central sulcus. These findings were indicative of a focal cortical dysplasia type-2. Subsequent genetic analysis through a gene panel identified the presence of an NPRL2 variant. Mutations affecting this particular gene are known to disrupt the normal functioning of the GATOR1 complex, potentially causing focal cortical dysplasia and various forms of epilepsy, including familial focal epilepsy with variable foci. On the diagnosis, the patient received levetiracetam, and the ictal episodes promptly ceased. At the most recent follow-up (at 4 years old), the patient remained free of seizures without the need for any treatment, and her neurodevelopment so far had exhibited no abnormalities. Considering the landscape of epilepsy-related GATOR1 variants, it is conceivable that this gene family may play a significant role in the pathogenesis of benign forms of focal reflex seizures, including bathing epilepsy.
