Pediatric neuroradiology can be a complex topic that often requires advanced training to master. Many residency programs are not affiliated with a major children's hospital, and the number of residency programs offering children's hospital rotations has decreased in light of the 2014 changes to the radiology curriculum structure brought on by the Core Examination. This educational exhibit examines the material specifically delineated in the Core exam study guide in a case-based fashion with an emphasis on advanced pathology less likely to be encountered during radiology residency.

Educational Goals / Teaching Points
The ABR Core Exam study guide section on pediatric neuroradiology is divided into systems and further into pathology groups. Case-heavy examples of disease processes with flowcharts and distinguishing features specifically designed to master the approach to differential diagnoses.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The exhibit is arranged in the order of the study guide. Craniosynostoses are classified by head shape with head growth along the plane of the prematurely closed suture. Dermoid cysts are recognizable by location and diffusion restriction. Scalp collections are localized by compartment tendency to cross sutures, and composition. Congenital brain, temporal bone, spine, and facial abnormalities are classified and illustrated. Neurocutaneous syndromes are detailed. Infectious processes are highlighted with attention to sequelae of intrauterine infection. Pediatric brain tumors are predominantly in the posterior fossa and generally exhibit imaging characteristics that improve specificity. Neonatal hypoxic ischemia and arterial strokes have different appearances, both of which have different characteristics compared to metabolic causes of diffusion restriction. Non-accidental trauma is a key diagnosis that must be raised in the setting of unexplained subdural hematoma.

Pediatric neuroradiology can be a daunting topic which may be associated with knowledge gaps for residents, particularly those without day-to-day experience with many of these disease processes.
