Hot water epilepsy (HWE) refers to a specific type of reflex epilepsy 
precipitated by the stimulus of bathing in hot water. Pathogenesis is still 
unknown and temporal lobe has been thought to take part in the epileptogenesis. 
HWE can be symptomatic of focal cortical malformation, and few cases were 
reported. This is the third report of HEW in which a parietal malformation has 
been observed. Our hypothesis that sensory cortex might be implicated in the 
epileptogenic process is corroborated by two previous reports on patients with 
HWE and malformation of the parietal cortical development.
