This Atlas is intended to assist the busy clinician in diagnosis, work-up and disposition. It was written for anyone who steps foot into a Pediatric Emergency Department and has the privilege of taking care of children. It is also the hope of the authors that the experiences we have had and the images we have captured will stimulate the clinicians who are starting their careers to never stop asking questions, always strive to improve the art of visual diagnosis, work on eliminating any fear of patient contact and never stop learning from your patients.
