This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background – COVID-19 associated Multisystem Inflammatory Syndrome in Children (MIS-C) is an emerging disease that presents with inflammation of multiple organs. The extracardiac radiographic manifestations of this syndrome are not well understood.Objective – We reviewed the radiologic findings of MIS-C in a cohort of children with a confirmed diagnosis of the syndrome.Materials and methods – In a retrospective study from 4/1/2020 to 5/22/2020, we reviewed imaging studies of 38 children with MIS-C, 21 females (55%) and 17 males (45%), with an average age of 9.2 years (range 1.3 – 20 years). Thirty six had chest radiographs, 6 had abdominal radiographs, 12 had abdominal sonograms or MRI, 2 had neck sonograms, and 3 had brain MRI.Results – 28 patients had pulmonary disease, with 24 (86%) having bilateral opacities, mostly diffuse (n=16, 57%). The most common abnormalities were peribronchial thickening (n=19, 68%), ground glass opacities (n=15, 54%) and consolidation (n=5, 18%). Pleural effusions were only present in children 10 years of age and under, and ground glass opacities were seen more often in older patients (59% vs. 26%, P<0.05). On abdominal imaging, small volume ascites was the most common finding (n=6, 50%). Other findings included right lower quadrant bowel wall thickening (n=3, 25%), gallbladder wall thickening (n=3, 25%), and cervical (n=2) or abdominal (n=2) lymphadenophathy. Of 3 patients with brain MRI, one had bilateral parietooccipital abnormalities and another papilledema.Conclusion – COVID-19 associated MIS-C causes a constellation of findings in the chest and abdomen, most often showing bilateral diffuse pulmonary abnormalities and small volume ascites.
