Abstract:
Two case reports demonstrating the need for enhanced usage of personal protective equipment of face shield, respirator, gloves, and gown during routine radiologic evaluation who may screen negative for COVID-19 and or atypical COVID-19 symptoms. First case is of a 42-year-old woman undergoing preoperative evaluation for endometrial cancer in the outpatient setting. The second case is of a 49-year-old woman presenting with abdominal pain, nausea, and vomiting for abdominal CT imaging from the emergency department. Both cases demonstrate typical lung imaging finding of COVID-19. These cases highlight the need for additional precautions in the outpatient and emergency setting even for patients in whom COVID-19 infection is not suspected.
