ABSTRACT
Background: Variable neuroimaging findings have been reported in patients with coronavirus disease 2019 (COVID-19). In addition to respiratory symptoms, many neurologic manifestations of COVID-19 are increasingly reported and variable neuroimaging findings have been observed in patients with COVID-19. Our aim was to describe findings observed in hospitalized patients with COVID-19, presenting with acute neurologic manifestations and undergoing computed tomography (CT) or magnetic resonance imaging (MRI) of the brain. Methods: We performed a retrospective study involving patients with laboratory-confirmed SARS-COV-2 infection, admitted to our hospital between July 1 and December 30, 2020. Patients who presented with acute neurologic symptoms and required neuroimaging were only included in the study. Neuroimaging examinations were evaluated for the presence of, infarction, hemorrhage and encephalopathy. The frequency of these findings was correlated with clinical variables, including presence of comorbidities, requirement for intensive care unit admission, and duration between admission and onset of neurologic signs and symptoms as documented in the hospital medical records. Results: A total of 135 patients underwent at least one cross-sectional imaging of the brain, the median age of these patients was 63 years, and 72% were men. Disturbed level of consciousness was the most common neurologic symptom (80.7%). Acute neuroimaging findings were found in 34 patients (25.2%) including;acute ischemic infarcts (16/135;11.9%), intracranial hemorrhages (9/135, 6.7%), cerebral venous thrombosis (2/135;1.5%), posterior reversible encephalopathy syndrome (1/135;0.7%), and hypoxic-ischemic encephalopathy (6/135, 4.4%). There was no statistically significant difference in patient age (p = 0.062), sex (0.257), presence of comorbidities (p = 0.204), intensive care unit admission (p = 0.326) and duration between admission and onset of neurologic signs and symptoms (p = 0.755), in patients with positive versus negative neuroimaging studies. Conclusions: Our study showed that cerebrovascular complications, ischemic and hemorrhagic were the most frequent imaging finding in hospitalized patients with COVID-19. Knowledge about these potentially serious complications can help optimize management for these patients.
ABSTRACT
Background: Corona virus disease 2019 (COVID-19) pandemic—as declared by the World Health Organization—is a major threatening public health problem. At the time of writing, more than 60,000,000 patients and more than 1,500,000 deaths were recorded worldwide. Besides the classical chest symptoms, gastrointestinal tract-related symptoms were noted, like diarrhea, abdominal distention, and hematochezia, adding more difficulties in the diagnosis of the disease. Although there are many publications evaluated, the thoracic imaging signs and complications of COVID-19, there are few articles—to the best of our knowledge—that evaluated the gastrointestinal tract imaging features and complications related to COVID-19. Results: In this retrospective study, positive COVID-19 patients who underwent diagnostic computed tomography (CT) for abdominal complaints along a 3-month duration in a large isolation hospital were evaluated. Strict infection control measures were taken during the CT examinations. The data were reviewed on picture archiving and communications systems with clinical data and laboratory result correlation. Thirty patients (30%) showed gastrointestinal (GI) findings, and 70 patients showed unremarkable or non-related GI findings. The 30 patients were classified into four groups: the ischemic group including 10 patients (10/30: 33.33%), the bleeding group included six patients (6/30: 20%), the inflammatory group included nine patients (9/30: 30%), and fluid-filled bowel group included five patients (5/30: 16.6%). Conclusions: COVID-19 should be evaluated as a systemic disease with extra pulmonary highlights. GI imaging should be considered for COVID-19 patients with related suspicious symptoms. Ischemic GI complications were the most common GI findings. © 2021, The Author(s).
