RESUMEN
In recent months, much of the scientific efforts have focused on research on SARSCoV-2 infection and its consequences in humans. Still, many aspects remain unknown. It is known that the damage caused by SARS-CoV-2 is multifactorial and that its extension goes beyond lung inflammation and the acute phase, with the appearance of numerous complications and sequelae. To date, knowledge about the usefulness of 18F-FDG-PET/CT in the acute phase has been limited to the incidental detection of SARS-CoV-2 unsuspected pneumonia. Recent studies have been appearing collecting the findings of 18F-FDG-PET/CT in long COVID-19 or persistent COVID-19 state as well as the alterations caused after mass vaccination of the population in the metabolic studies. This work aims to review the existing literature focusing on these three issues and to briefly present our own preliminary experience.

La actinomicosis es una enfermedad crónica granulomatosa infrecuente causada por Actinomyces spp, una bacteria anaerobia gram positiva que normalmente coloniza la boca, genitales y tracto digestivo en humanos1. En la mayor parte de los casos, la enfermedad se manifiesta en la región cervicofacial. Sin embargo, se han descrito varios casos en los que la actinomicosis puede simular procesos malignos en localizaciones no comunes, como en el pulmón. Se presenta el caso de una paciente con un cuadro constitucional de 20 días de evolución con una masa paramediastínica, a la que se le diagnostica de actinomicosis pulmonar tras una lobectomía por sospecha clínica de malignidad
Actinomycosis is a rare chronic granulomatous disease caused by Actinomyces spp, an anaerobic gram positive bacteria that colonizes mouth, large bowel and genitals. Actinomycosis occurs most frequently at oral and cervicofacial region. Less commonly affected areas include thoracic, abdominal, pelvic and central nervous system. We report a case about a patient with constitucional syndrome and a paramediastinal ma ss who was diagnosed with pulmonary actinomycosis after a lobectomy because of clinical suspicion of malingnancy
