ABSTRACT

Al igual que las células malignas, las células inflamatorias pueden captar intensamente 18F-fluorodesoxiglucosa (FDG). La reacción inflamatoria ganglionar axilar se ha descrito en forma creciente y globalmente luego de la vacunación contra COVID-19 con las vacunas de Pfizer, Moderna y AstraZeneca, en pacientes con cáncer. Se presentan dos casos con diagnóstico de cáncer de ovario y mama, respectivamente, con antecedente de vacunación reciente contra COVID-19, en quienes el estudio de PET/TC muestra ganglios linfáticos axilares hipermetabólicos con FDG. A continuación, se describen los hallazgos clave para interpretar el realce aumentado de los ganglios linfáticos axilares en pacientes con cáncer que han sido vacunados contra este virus.


Like malignant cells, inflammatory cells can intensely take upF18-fluorodeoxyglucose (FDG). The axillary lymph node inflammatory reaction has been increasingly and globally described after vaccination against COVID-19 with the Pfizer, Moderna and AstraZeneca vaccines, in cancer patients. We present two cases with a diagnosis of ovarian and breast cancer respectively, with a history of recent vaccination against COVID-19, in whom the PET/CT study present hypermetabolic axillary lymph nodes with FDG. Key findings for interpreting increased axillary lymph node uptake in cancer patients who have been vaccinated against this virus are described below
