BACKGROUND: The distal tibia is a common location for the classic metaphyseal lesion (CML). Prior radiologic-pathologic studies have suggested a tendency for medial, as opposed to lateral, cortical injury with the CML, but there has been no formal study of the geographic distribution of this strong indicator of abuse. OBJECTIVE: This study compares medial versus lateral cortical involvement of distal tibial CMLs in a clinical cohort of infants with suspected abuse...

Perceptual errors are common contributors to missed diagnoses in the clinical practice of radiology. While the physical attributes of an image such as image resolution, signal-to-noise characteristics, and anatomic complexity are major causes of poor conspicuity of pathologic lesions, there are major interrelated cognitive contributors to visual errors. The first is satisfaction of search (SOS), where the detection of an abnormality results in premature termination of further search. Another form of incomplete search pattern is visual isolation, where a radiologist's search pattern is truncated to the main areas of an image, while little or no attention is given to peripheral areas...

PURPOSES: Kaposiform hemangioendothelioma (KHE) is a unique locally aggressive vascular tumor with poor prognosis. The aim of this study is to assess the clinical and imaging features of KHE, and to compare the differences between solitary and diffusive infiltrative subtype further. METHODS: The clinical and radiological findings of a cohort of 25 cases with histologically proven KHE, between June 2011 and June 2016, were reviewed retrospectively. Seven solitary and 18 diffusive infiltrative subtypes KHE were included...

Epiploic appendagitis, caused by inflammation of small adipose tissue on the colon wall, is a rare cause of acute abdominal pain in the pediatric population. It is nearly impossible to establish a specific diagnosis merely on the basis of clinical findings; thus, radiological evaluation is always necessary. In this report, we present the cases of three children with abdominal pain who were diagnosed with epiploic appendagitis. All cases were successfully treated with conservative management.

Nexplanon is a long-acting 4cm radio-opaque rod shaped contraceptive device implanted in the subdermal layer of the inner, upper arm. Complications from implantation are uncommon and mostly local and minor, including infection at the implantation site with resulting cellulitis or abscess, hematoma, abnormal scar formation, or local damage to nerves and blood vessels. Intravascular insertion is estimated to be at 1.3 per million Nexplanon implants, and migration and embolization is a rare complication of this device...

Radiological assessment of the head is a routine part of the management of traumatic brain injury. This assessment can help to determine the requirement for invasive intracranial pressure (ICP) monitoring. The radiological correlates of elevated ICP have been widely studied in adults but far fewer specific pediatric studies have been conducted. There is, however, growing evidence that there are important differences in the radiological presentations of elevated ICP between children and adults; a reflection of the anatomical and physiological differences, as well as a difference in the pathophysiology of brain injury in children...

INTRODUCTION: Spinal tuberculosis [TB] is a common infectious disease prevalent in developing countries and a rising disaster in developed countries. The association of tuberculosis with spondylolisthesis is rarely reported in literature. The aim of our review is to analyse the clinical features and radiologic characteristics of TB spondylolisthesis along with providing a concise update on its surgical management, based on current literature. METHODS: A systematic review is performed after conducting a thorough search in the PubMed database...

OBJECTIVES: General anesthesia or sedation can facilitate the completion of diagnostic radiological studies in children. We evaluated the incidence, predictors, and causes of adverse events (AEs) when general anesthesia is provided for diagnostic radiological imaging. METHODS: Deidentified data from 24 pediatric tertiary care hospitals participating in the Wake-Up Safe registry during 2010-2015 were obtained for analysis. Children 18 years or younger receiving general anesthesia for radiological procedures were identified using Current Procedural Terminology codes, and reported AEs were analyzed if they were associated with anesthetic care at magnetic resonance imaging or computed tomography locations...

Various shoulder bone deformities have been identified in the pediatric age group, with the most common being undescended scapula. Sprengel's deformity is dysplasia and malposition of the scapula, especially in the supraspinatus portion, mainly due to abnormal descent in the embryonic period. The clavicle is shorter and has a different contour. In some patients cervical spine deformities are also noted. This is a case of 3 years old girl presented to the clinic with difficulty in abducting right shoulder and sleeping with an internal rotation of the right arm...

PURPOSE: To determine the impact of intravenous (IV) gadolinium in assessment of pediatric IBD by MRE. STUDY TYPE: Retrospective, case series. POPULATION: Radiology information system was searched to identify all children who underwent MRE and endoscopy within 30 days in 2016...

OBJECTIVE: To review tracheal paragangliomas and describe the clinical presentation, radiologic findings, operative management, and histologic findings of a pediatric patient who presented with stridor refractory to traditional asthma therapy. METHODS: Chart review of an 8-year-old male who presented to a tertiary care pediatric hospital and literature review of tracheal paragangliomas. RESULTS: We present the case of an 8-year-old male who presented with new-onset of wheezing and dyspnea on exertion...

OBJECTIVE Tumor-related edema of the optic tract (EOT) corresponds to a preferential posterior distribution of peritumoral edema along the white matter tract of the visual system. To date, the consequences of EOT have never been evaluated specifically in the pediatric population. In this study, the authors attempted to identify clinical and radiological features associated with the development of EOT and the specific influence of this edema on visual function. METHODS A retrospective review was performed of data collected from patients younger than 18 years who underwent surgery for a tumor in the sellar region at the authors' institution between January 2005 and January 2016...

BACKGROUND: Diagnosis of TB in children is challenging, and is largely based on positive history of contact with a TB case, clinical and radiological findings, often without microbiological confirmation. Diagnostic efforts are also undermined by challenges in specimen collection and the limited availability of high sensitivity, rapid diagnostic tests that can be applied with a quick turnaround time. The current project was undertaken in four major cities of India to address TB diagnostic challenges in pediatric population, by offering free of cost Xpert testing to pediatric presumptive TB cases, thereby paving the way for better TB care...

OBJECTIVE: Lung disease is a common indication for newborns to require medical attention, and neonatal chest radiographs are among the most common studies interpreted by pediatric radiologists. Radiographic features of many neonatal lung disorders overlap, and it may be difficult to differentiate among conditions. CONCLUSION: This review presents an up-to-date practical approach to the radiologic diagnosis of neonatal lung disorders, with a focus on pattern recognition and consideration of clinical history, patient age, and symptoms...

OBJECTIVE The relationship between a tethered cord (TC) and neurofibromatosis type 1 (NF1) and NF2 is not known. The purpose of this study was to define the incidence of TC in pediatric neurosurgical patients who present with NF. METHODS The authors performed a single-institution (tertiary care pediatric hospital) 10-year retrospective analysis of patients who were diagnosed with or who underwent surgery for a TC and/or NF. Clinical and radiological characteristics were analyzed, as was histopathology. RESULTS A total of 424 patients underwent surgery for a TC during the study period, and 67 patients with NF were seen in the pediatric neurosurgery clinic...
