Aerophagia and subcutaneous emphysema in a patient with Rett syndrome.
Overview
abstract
A patient with Rett syndrome presented to our Emergency Department with extensive subcutaneous emphysema in the cervical region, chest wall, upper extremities, and back. Diagnostic evaluation revealed a mucosal tear in the posterior pharyngeal wall and an abscessed retropharyngeal lymph node, but she had no known history of trauma to account for these findings. This report discusses the occurrence of subcutaneous emphysema in the context of a rare neurodevelopmental disorder and proposes accentuated aerophagia, a sequela of Rett syndrome, as the most likely underlying mechanism.
