A Case of Periventricular Nodular Heterotopia with Late Onset Seizures

Periventricular nodular heterotopia is a neuronal migration disorder that may manifest itself by epileptic seizures starting generally at 2nd and 3rd decades. Most patients appear mentally and physically normal, but some of them may have multiple findings, including short-gut syndrome, language disturbances, and mild to severe mental retardation. Here, we present a case with bilateral periventricular nodular heterotopias that starts to seize after fourth decade which in our knowledge, is the oldest age to experience the first seizure in this circumstances.
