CTICasesReactive Lymphadenopathy in COVID-19 Pneumonia
Imaging findings
CT chest in a patient with acute COVID-19 pneumonia demonstrates progression of bilateral peripheral consolidations and ground-glass opacities, accompanied by the rapid development of mild, generalized hilar and mediastinal lymphadenopathy over a 2-day period.
Key takeaways
While lymphadenopathy is relatively uncommon in typical COVID-19 infection, severe cases can show rapid development of reactive mediastinal and hilar lymph node enlargement. This represents a normal inflammatory response and should not be mistaken for lymphoma, sarcoidosis, or secondary bacterial superinfection.
