ABSTRACT
A 55-year-old asymptomatic woman with newly diagnosed, locally advanced breast cancer undergoing routine staging with 2-deoxy-2[18F]fluoro-d-glucose positron emission tomography/computed tomography was found to have multiple hypermetabolic pulmonary nodules on imaging that were concerning for metastatic disease. However, further workup with dedicated chest computed tomography imaging demonstrated multiple bilateral, peripheral nodular lesions with peripheral ground-glass opacity, predominantly in the lower lung zone, that were suspicious for coronavirus disease 2019. The patient ultimately was diagnosed with coronavirus disease 2019 based on detection of viral ribonucleic acid via polymerase chain reaction. Follow-up chest computed tomography scan obtained after 27 days showed complete resolution of the lung lesions. In the setting of a global pandemic, a high index of suspicion for coronavirus disease 2019 in cancer patients is warranted, not only to enable early identification and treatment of a potentially aggressive infection but also to prevent misdiagnosis of metastatic disease.
