We present the case of a 14-year-old boy presented with a recent history of progressive neurologic decline and extrapyramidal features. The history and findings with illustrative figures are detailed, and a diagnostic approach to the presentation is considered. The therapeutic options and broader management issues are briefly reviewed.
