Coronavirus disease 2019 (COVID-19) can present with abdominal pain in children and adults. Most imaging findings have been limited to characteristic lung findings, as well as one report of bowel-ischemia-related findings in adults. We report a case of COVID-19 in a healthy teenager who initially presented with isolated mesenteric adenopathy, typically a self-limited illness, which progressed to severe illness requiring intensive care before complete recovery. The boy tested negative for COVID-19 twice by polymerase chain reaction (PCR) from upper respiratory swabs before sputum PCR resulted positive. A high index of suspicion should be maintained for COVID-19 given the continued emergence of new manifestations of the disease.
