    Abstract Neurological complications are frequently mentioned in the published reports regarding the coronavirus disease 2019 (COVID-19). Especially encephalopathy draws attention as the leading symptom or complication of COVID-19 in some reports. This article discussed a 3-year-old patient with bilateral lentiform and caudate nuclei involvement on brain imaging, who presented with mental status changes and acute muscular weakness, possibly due to COVID-19. To the best of our knowledge, this case is the first one showing pathological signal enhancement and edema in bilateral lentiform and caudate nuclei associated with COVID-19.

    Abstract Background: Transverse myelitis (TM) is a very uncommon condition in children which can be associated with viral infections. Acute TM cases have been reported after Coronavirus disease 2019 (COVID-19) infection during the pandemic.
    Case report: We report a child with TM related to severe acute respiratory syndrome coronavirus 2, who was successfully treated with therapeutic plasma exchange (TPE). Inability to walk and urinary retention were the central nervous system symptom. Spinal magnetic resonance imaging revealed signal changes in the spinal cord. Her neurological symptoms worsened despite receiving IVIG and high-dose steroids for the first 3 d. We performed 10 TPE sessions with 5% albumin replacement and the neurological symptoms rapidly improved.
    Conclusion: We demonstrated that a child diagnosed with acute TM related to COVID-19 infection, was successfully treated with TPE.

    Abstract Aim: To evaluate the effect of intensive care follow-up and treatment methods on the prognosis of 28 patients admitted to the pediatric intensive care unit (PICU) due to stroke.
    Material and methods: The data of patients aged between 28 days and 18 years followed up between 2011 and 2021 were recorded retrospectively.
    Results: Thirteen (48.1%) patients were diagnosed with hemorrhagic stroke (HS), 11 (40.7%) patients were diagnosed with acute ischemic stroke (AIS), and three (11.1%) patients were diagnosed with cerebral sinus vein thrombosis. One patient was followed up for non-ruptured arteriovenous malformation (AVM) and was excluded from the HS group. The HS group consisted of eight patients with ruptured AVMs and five patients with ruptured intracranial aneurysms. The patients had male predominance, and seizures and headache were the most common complaints on admission. The rate of admissions due to seizures was higher in the AIS group. In the HS group, there was more involvement of the right side of the brain. Middle cerebral artery (MCA) involvement was higher in the AIS group. The AIS group had longer PICU hospitalization days and mechanical ventilator days. While unfractionated heparin was preferred for the treatment in the AIS group, endovascular embolization was preferred in the HS group. Decompressive surgery was performed in five patients. The overall mortality rate was 7.1%.
    Conclusion: Although cerebrovascular events are rare in the pediatric population, achieving low mortality and morbidity is possible with the correct diagnostic and treatment methods.

    Abstract Coronavirus disease (COVID-19) is caused by a novel severe acute respiratory syndrome coronavirus 2 virus which primarily targets the lungs. However, the central nervous system (CNS) and peripheral nervous system involvement due to COVID-19, however, has been reported as early as the cases of respiratory system involvement. In addition, there have been many reports describing neuroimaging features of COVID-19, but data beyond case studies in the pediatric population are still limited, indicating limited CNS involvement. The CNS involvement and complications include, but are not limited to, encephalopathy, meningoencephalitis, ischemic stroke, venous sinus thrombosis, acute necrotizing encephalopathy, acute disseminated encephalomyelitis, posterior reversible encephalopathy syndrome, acute cerebellitis, acute hemorrhagic myelitis, and Guillain–Barré syndrome. In this manuscript, we will discuss the imaging characteristics of some of these entities with a known diagnosis of COVID-19.

    Abstract Background: Real time shear-wave elastography (SWE) is a non-invasive imaging method which can quantitatively assess liver stiffness. Obesity and its complication are increasing with improving lifestyles in our century. We evaluated the performance of SWE for detecting liver changes (fatty liver, steatohepatitis) in obese and overweight children, in addition to this, we determined the diagnostic accuracy and clinical usefulness of SWE in non-alcoholic fatty liver disease (NAFLD).
    Methods: Obese and overweight 41 children within the age range of 6-15 years were included in this singlecenter prospective study. Biochemical evaluation for aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride (TG), total cholesterol (TC) levels, as well as conventional ultrasound and SWE of the liver were performed in the patient group. These values were compared with values of 25 normal weight and healthy children in the age range of 6-16 years.
    Results: The mean SWE values was 13.7 ± 5.5 kiloPascal (kPa) and 2.03 ± 0.35 meter/second (m/s) in patient group and 7.99 ± 2.81 kPa and 1.62 ± 0.21 m/s in control group (p < 0.01). The receiver-operating characteristics (ROC) analysis was performed to determine the optimum cut-off value for elastography values (kPa) to evaluate liver changes; area under the curve was 87.5% (95% CI 79.3-95.8). When the cutoff value was set as 10.45 kPa, the sensitivity and the specificity was 69.2% and 100%, respectively. We could not observe a statistically significant difference when we compared the elastography values (kPa and m/s) according to presence of hepatosteatosis (p=0.581 and 0.172). There were no significant correlations between SWE and AST, ALT values.
    Conclusions: SWE may be a useful and accurate imaging method to evaluate liver changes and monitor NAFLD in obese and overweight children.

    Abstract The Coronavirus disease-2019 (COVID-19) in children is more likely to be asymptomatic or to have mild-to-moderate symptoms; however, severe cases have also been reported. A 10-year-old boy previously diagnosed with pontocerebellar hypoplasia presented with respiratory distress after 2 days of fever. He underwent tracheal intubation. He was COVID-19 positive. On day 10, a cystic area was observed in his chest radiography and thorax computer tomography also showed a thick-walled pulmonary abscess. Percutaneous empyema drainage was performed. On day 20, an open surgical tracheotomy was performed. On day 25, the percutaneous drainage catheter was removed. On day 55, he was discharged on the home ventilator and his chest radiography was normal. Children with COVID-19 may develop a pulmonary abscess secondary to superinfections during intensive care follow-up.

    Abstract Imaging plays an important role in determining indications of cochlear implantation and choosing candidates for the procedure in children. Temporal high-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) can display precisely the complex anatomic structure of inner ear. Although HRCT permits detailed imaging of bony structures, MRI gives valuable information about membranous labyrinth, internal acoustic canal, and vestibulocochlear nerve. Magnetic resonance imaging examination of the brain should be performed at the same time to evaluate any coexistent brain parenchymal abnormality. These imaging modalities are complementary methods in evaluating congenital inner ear anomalies. The aim of this pictorial essay is to reviewing temporal HRCT and MRI findings of congenital inner ear anomalies.

    Abstract Rationale and objectives: To retrospectively evaluate imaging findings in multisystem inflammatory disease in children associated with COVID-19 (MIS-C).
    Materials and methods: The radiological imaging findings of 45 pediatric patients aged between 52 days and 16 years, who were diagnosed with MIS-C according to the World Health Organization (WHO) criteria, were evaluated. All the patients underwent chest X-ray and echocardiography. The findings obtained from 25 abdominal radiographs, 24 abdominal US, 7 abdominal CT, 16 thorax CT, 21 cranial MRI and one spinal MRI, MR cholangiography (MRCP) and cardiac MRI examinations were categorized and evaluated according to the affected systems.
    Results: While the most common findings in chest X-ray were perihilar opacity and peribronchial thickening, pleural effusion was the most finding in thorax CT. Echocardiography findings of myocarditis were observed in 31% of the cases. The most common findings in abdominal radiological evaluation were hepatomegaly and splenomegaly, edema in the gallbladder wall and periportal area, mesenteric lymph nodes in the right lower quadrant, thickening of the intestinal walls, and free fluid. Reversible splenial lesion syndrome (RESLES) was the most common neurological finding. Acute disseminated encephalomyelitis (ADEM)-like lesions, acute hemorrhagic necrotizing encephalomyelitis, and radiological findings consistent with Guillain-Barré syndrome were found in one case each.
    Conclusion: Radiological findings seen in MIS-C in pediatric cases are correlated with the affected system. According to the system involved, there is no specific finding for this disease. Radiological findings are not the primary diagnostic tool but can assist in the evaluation of the affected systems and to guide treatment.
