Landau-Kleffner Syndrome: an Uncommon Dealt with Case in Southeast Asia

An 11-year-old boy was admitted with fever followed by convulsions. He had developed aphasia subsequent to this illness. His birth history was unremarkable, and he had normal growth and development including of language, hearing and vision. His neurological examination was normal except for aphasia. Investigations including cerebrospinal fluid study and MRI were normal. However, EEG was abnormal and the boy was diagnosed as a case of Landau-Kleffner syndrome (LKS) and treated with sodium valproate, levetiracetam and steroids. He responded well to treatment and has been on follow-up for the last 4 months. We present this case of LKS to increase awareness about early diagnosis and to highlight the importance of appropriate management for a better outcome.
