Persistent hyperinsulinemic hypoglycaemia followed as benign infantile convulsion.
An 18-month-old boy developed seizures at 3 months of age. He developed normally and, his EEG and brain CT revealed no abnormal findings. The blood sugar level was normal at that time, thus he was diagnosed as having benign infantile convulsion. At 7 months of age seizures reappeared, and hypoglycaemia associated with hyperinsulinism was observed during the seizures. With conservative therapy his blood sugar level was well controlled and he had no further seizures. Hypoglycaemic seizures are sometimes misdiagnosed as epilepsy. We have to pay attention to hyperinsulinemic hypoglycaemia when we see seizures with normal EEG even in infants.
