This case series examines the spectrum of imaging findings at chest radiography, US, CT, and MRI in 35 children admitted to a tertiary pediatric hospital in April and May 2020 with a post–coronavirus disease 2019 inflammatory condition known as multisystem inflammatory syndrome in children. The constellation of findings includes airway inflammation and rapid development of pulmonary edema on thoracic images, coronary artery aneurysms, and extensive right iliac fossa inflammatory changes on abdominal images. Awareness of this emerging condition and the expected multi-organ imaging findings will aid radiologists in the assessment of these complex cases. © RSNA, 2020

IDHs may be the presenting factor in children with unsuspected bleeding problems. We present these findings to raise awareness of the imaging features and clinical impact of these cases because better understanding of these risk factors may help to avoid these complications in children in the future.

Henoch-Schonlein purpura is a vasculitis affecting small arterial vessels. Occasionally, cases are referred for a general surgical opinion due to bowel involvement in the form of abdominal pain with or without rectal bleeding. However, surgical intervention is rarely required. We describe a case of Henoch-Schonlein purpura in a young man who went on to develop ischaemic bowel requiring resection.
