Abstract:
The most common features of coronavirus disease-2019 (COVID-19) pneumonia on chest computed tomography imaging are ground glass opacity and consolidation. Mediastinal and hilar lymph node enlargement are less frequently observed. Herein, we present an unexpected finding of fluorodeoxyglucose (FDG)-avid hilar lymph node in an asymptomatic patient with COVID-19, and show that this is a transient phenomenon, subsiding on a follow-up FDG-PET/CT within 10 days.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
