T2/FLAIR mismatch and diffusion restriction as novel pathophysiological markers in MRI evaluation of central tegmental tract hyperintensity in pediatric patients.

Introduction: Central tegmental tract hyperintensity (CTTH) on T2-weighted imaging is an uncommon neuroimaging finding in pediatric patients with unclear clinical significance. CTTH may represent either a physiological or pathological process. This study evaluates the relationship between CTTH and MRI sequences (FLAIR, DWI) to explore its diagnostic value.

Correlation between early computed tomography findings and neurological outcome in pediatric traumatic brain injury patients.

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Head computed tomography (CT) is frequently utilized for evaluating trauma-related characteristics, selecting treatment options, and monitoring complications in the early stages. This study assessed the relationship between cranial CT findings and early and late neurological outcomes in pediatric TBI patients admitted to the pediatric intensive care unit (PICU).

Clinical and Imaging Clues of Arteriopathy-Related Pediatric Arterial Ischemic Stroke: A Single Center Experience.

Background And Purpose: Arteriopathy is a common etiology for childhood arterial ischemic stroke (AIS). In this study, we aimed to address clinical, demographic, and neuroimaging characteristics and the reversibility of vasculopathy in patients with childhood stroke due to arteriopathy by classifying them according to Childhood AIS Standardized Classification and Diagnostic Evaluation (CASCADE) criteria.

Methods: We included 15 patients with AIS due to arteriopathy presented between 2013 and 2018.

A Rare Case of "Periportal Cuffing" as an Incidental Finding on F-FDG PET/CT.

A 7-year-old boy with known diagnosis of hereditary spherocytosis and ulcerative colitis was referred for F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography after detection of a 28 mm lesion suspicious for malignancy in spleen on upper abdomen magnetic resonance imaging (MRI). As an incidental finding, a moderately increased uptake of F-FDG was observed in periportal region with no definable mass. MRI revealed compatible findings with "periportal cuffing" as described on ultrasonography.

Childhood-Onset Sacroiliitis: Causes and Correlation Between Clinical Findings and Magnetic Resonance Imaging.

Objective: The aims of this study were to describe disease associations of magnetic resonance imaging (MRI)-confirmed and clinically symptomatic sacroiliitis in pediatric patients with rheumatic diseases and to examine the relationship between patient characteristics and MRI findings of the sacroiliac joint (SIJ).

Methods: Demographic and clinical data were extracted from the electronic medical records of the patients with sacroiliitis followed in the last 5 years. Active inflammatory and structural damage lesions of the SIJ-MRI were examined by the modified Spondyloarthritis Research Consortium of Canada scoring system, and correlation analysis of these results with clinical characteristics was evaluated.

The unique features of middle cranial fossa and Sylvian fissure arachnoid cysts in children: MRI evaluation.

Purpose: The purpose of the study is to evaluate MRI findings of middle fossa arachnoid cysts in children according to Galassi classification and determine the differences between types and to assess the morphological changes in cysts during follow-up imaging.

Methods: MR images of 266 middle fossa arachnoid cysts of 255 pediatric patients were evaluated by two experienced radiologists retrospectively. MRI features including the sidedness of the cyst, Galassi type, parenchymal compression findings (cortical flattening and white matter compression), bone remodeling, and midline shift were evaluated on axial T2- and T1-weighted images.

Multisystem inflammatory syndrome in children associated with SARS-CoV-2: extracardiac radiological findings.

Objective: Multisystem inflammatory syndrome in children (MIS-C) is seen as a serious delayed complication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The aim of this study was to describe the most common imaging features of MIS-C associated with SARS-CoV-2.

Methods: A retrospective review was made of the medical records and radiological imaging studies of 47 children (26 male, 21 female) in the age range of 25 months-15 years who were diagnosed with MIS-C between August 2020 and March 2021.

Value of strain-wave sonoelastography as an imaging modality in assessment of benign acute myositis in children.

Background/aim: Although sonoelastography is applied in assessment of many organs, studies for evaluation of muscles are very few in number and are mostly limited to adults. With this prospective study, we aimed to evaluate the value of sonoelastography in assessment of influenza related benign acute myositis in children.

Materials And Methods: This study enrolled 25 patients with a clinical diagnosis of benign acute childhood myositis (BACM) and 25 age and sex-matched healthy controls.

Interpeduncular Heterotopia and Brain Stem Cleft: An Isolated Finding Not Associated with Joubert Syndrome.

Interpeduncular heterotopia is a new neuroimaging finding reported in association with Joubert syndrome (JS) in a few cases in the literature. Nodular interpeduncular tissue was termed as interpeduncular heterotopia and anterior mesencephalic cap dysplasia in the literature in relation to gray and white matter content. We described the imaging findings and diffusion tensor imaging data of a case with interpeduncular heterotopia and brain stem cleft.

Behçet's Disease and Intracardiac Thrombosis: A Report of Three Cases.

We present three patients with Behçet's disease associated with intracardiac thrombus and pulmonary vascular involvement. One of these patients had also Budd-Chiari syndrome. All patients were treated with corticosteroid plus monthly intravenous cyclophosphamide as first line treatment and with no recurrences.
