Late onset epilepsy in undiagnosed tuberous sclerosis

A 67 year old woman first developed left-sided sensorimotor seizures postoperatively in association with infection and mild hyponatraemia. She was found to have previously unrecognized tuberous sclerosis, with gross pathognomic features: periungual fibromata, facial angiofibromata, calcified subependymal nodules, cortical tubers and multiple renal angiomyolipomata. Her son who was epileptic was also found to have other mild features of tuberous sclerosis as a result. As far as we are aware our patient is the oldest for the first presentation of tuberous sclerosis.
