Urinary tract dilation (UTD) is a common finding in fetal and neonatal imaging, and accurate classification is essential for guiding management and determining prognosis. This educational exhibit provides a comprehensive review of the UTD classification system, with a focus on the findings on fetal ultrasound (US), fetal MRI and postnatal imaging. In addition to the classification system, we will explore the etiologies of UTD, including obstructive and non-obstructive causes such as vesicoureteral reflux, ureteropelvic junction obstruction, and posterior urethral valves. Special emphasis will be placed on the role of prenatal and postnatal imaging in monitoring progression and guiding management decisions, including when surgical intervention may be necessary. We aim to enhance the understanding of the diagnostic criteria for UTD, provide insight into the correlation between imaging findings and clinical outcomes, and equip pediatric radiologists with the tools to make informed management recommendations. This review will aid in the accurate diagnosis and treatment of UTD, ultimately improving outcomes for affected neonates. Read More

The diagnosis of non accidental trauma (NAT) has significant clinical, therapeutic and social implications for the patient and the family. The recognition of suspicious fractures and fracture patterns, in conjunction with the clinical findings, plays an important role in the accurate diagnosis. However, there are congenital, metabolic and infectious processes that can mimic skeletal findings of NAT. Radiologists must be cognizant of these mimics and recognize the imaging and clinical findings that differentiate them from NAT to ensure accurate diagnosis and appropriate intervention. This educational exhibit aims to elucidate the key radiographic features and clinical presentations that distinguish NAT from conditions that can mimic its appearance, such as osteogenesis imperfecta, rickets, and metabolic bone diseases. Through a series of case studies and imaging examples, we will explore the skeletal findings of NAT mimics and compare them with the common fracture patterns associated with NAT, highlighting the imaging and clinical findings that differentiate the two. We will emphasize the importance of a thorough patient history and multidisciplinary approach in evaluating suspected cases of abuse. By understanding the nuances of NAT mimics, radiologists can improve their diagnostic acumen, reduce the risk of misdiagnosis, and ultimately contribute to better patient outcomes. Read More
