Pediatric Post-Pump Chorea: Case Report and Implications for Differential Diagnosis.

Background: Chorea is a neurological disorder characterized by random, fluid movements that may affect the limbs, trunk, neck, or face. In children, Sydenham's chorea (SC) is the most common cause of acute chorea, mainly following group A beta-hemolytic streptococcal (GABHS) infection. Other autoimmune and metabolic disorders may also cause chorea.
