Hypothalamic hamartoma, gelastic epilepsy, precocious puberty – a diffuse cerebral dysgenesis

Childhood epileptic syndrome characterized by early onset gelastic seizures, hypothalamic hamartoma and precocious puberty is well recognized though rare. We report association of agenesis of corpus callosum, Dandy–Walker complex and heterotopic gray matter with this childhood epileptic syndrome which is hitherto an unreported association. The child showed a satisfactory response to gonadotropin releasing hormone agonist.
