From: Hypermetabolic lymphadenopathy following the administration of COVID-19 vaccine and immunotherapy in a lung cancer patient: a case report

Fig. 1

A 61-year-old woman with Stage IV carcinoma of the right lung receiving maintenance immunotherapy had PET–CT scan imaging (a) approximately 15 months prior to receiving her COVID-19 booster vaccination. PET–CT scan imaging of the same woman performed 2 weeks following COVID-19 booster vaccinations (b). Imaging reveals mixed response to treatment with a new left-sided level Xa retroauricular lymph node (1.5 × 1.8 cm, SUVmax 20), interval decrease in the size of the multilevel bilateral subcentimeter cervical chain lymph nodes without FDG uptake, and a right-sided level III lymph node measuring 1 cm with max SUV 8.0 (previously 8 mm and SUVmax 8.5). Interval increase in the size of the hypermetabolic level IVa lymph node measuring 1.8 cm with SUVmax 14.8 (previously 8 mm, SUV 5.3); and new left supraclavicular hypermetabolic lymph node measuring 8 mm with SUVmax 14.6
