Background. Mild encephalopathy with a reversible splenial lesion (MERS) is a known clinical-radiological description. However, MERS with extensive lesions (MERS type-2) is rarely associated with adenovirus. There are only three published cases of MERS type-2 associated with adenovirus infection.Case. We present a 10-year-old previously healthy girl who presented with speech difficulty and mild encephalopathy after three days of prodromal illness. The magnetic resonance imaging (MRI) revealed bilateral diffusion restriction in the parietal white matter, splenium and genu of the corpus callosum without mass effect and slight thickening at the splenium of corpus callosum with no contrast enhancement. With empirical and support treatment, her neurological examination was completely normal by the 18th hour. The nasopharyngeal respiratory adenoviral PCR resulted positive. She was discharged with total clinical and radiological resolution on the 10th day of admission. The case was diagnosed with MERS type-2 which is rarely associated with adenoviral infection. Conclusion.This report is the first case of adenovirus related MERS type-2 in a Turkish child. Pediatricians, child neurologists, child infection specialists and radiologists should recognize this condition to ensure appropriate diagnosis.

Background/aim: This study objected to compare the measurements of corpus callosum substructures of adolescents with migraine and healthy adolescents. Materials and methods:In a case-control design, adolescents aged 12-18 years with the diagnosis of migraine and healthy control group had brain magnetic resonance imaging examination. The CC dimensions including anteroposterior length, truncus, genu and splenium widths of the case and control groups were measured and compared. Results:The sample consisted of 188 adolescents, 109 girls (58.0%) and 79 boys (42.0%). Of these 87 (46.3%) were in the migraine group and 101 (53.7%) were in the healthy control group. The mean genu and splenium width of the migraine group were significantly lower than the control group (p=0.024 and p=0.01 respectively). Conclusion:The results of this study firstly demonstrated that CC splenium and genu widths were smaller in adolescents with migraine when compared to healthy adolescents. Our findings may contribute to enlighten migraine pathophysiology.

Aim: We aimed to examine the diagnostic power of chest computerized tomography (CT) comparing with ‘Clinical Decision’ and RT-PCR results among the patients admitted to the hospital with COVID-19 disease suspicion. Material and Method: This study included 162 patients who applied to the pandemic outpatient clinic between March 11 and April 11, 2020, suspected of new coronavirus infection, and had chest CT and RT-PCR tests at the same time. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy and positive odds ratio of RT-PCR and chest CT imaging are investigated for the diagnosis of COVID-19. Results: It was found that 56.8% (92 patients) of chest CT scans taken at admission were compatible with viral pneumonia. With the ‘Clinical Decision’, which we accept as the gold standard diagnostic method, 61.1% of the patients (99 patients) were evaluated as COVID-19 positive and treatment was started. According to clinical decision, sensitivity of chest CT was 92.9%. Conclusion: COVID-19 pneumonia is a serious life-threatening condition. Rapid diagnosis and early treatment are very important in terms of reducing mortality and morbidity. The chest CT might create an early diagnosis and treatment opportunity.
