99mTc-Leukocyte Scintigraphy Revealed Viral Pulmonary Infection in a COVID-19 Patient.

ABSTRACT

Tc-leukocyte scintigraphy was performed on a 40-year-old woman with spiking fevers. A focus of intense uptake in the right upper thorax was identified, concerning for infection along the central line in the superior vena cava. Additionally, heterogeneously increased uptake in both lungs was noted, which suggested pulmonary infection. CT images of the chest showed patchy ground-glass changes in both lungs and a large consolidation in the right lower lobe, which were consistent with changes for COVID-19 (coronavirus disease 2019). Severe acute respiratory syndrome coronavirus 2 RNA test was positive. This case demonstrates that leukocyte uptake in bilateral lungs could reveal viral pulmonary infection in COVID-19.
