Abstract

A 10-month-old boy presented with a 1-day history of flaccid quadriplegia and dysconjugate gaze. His history was remarkable for stereotyped episodes of flaccid quadriplegia or hemiplegia, oculomotor abnormalities, and limb or neck posturing, beginning in the first days of life and becoming more frequent and more prolonged over time. The patient was healthy and developmentally normal between episodes. Results of extensive laboratory evaluations, including EEG and brain imaging studies, were negative. The patient's history, diagnostic evaluation, and final diagnosis are reviewed. This case illustrates the importance of a fundamental understanding of neurologic localization in pediatric care and a focused diagnostic approach to an infant with paroxysmal neurologic signs.
