What is your diagnosis? (58)
%%RATING%%
The histopathological study shows that it is a focal area of pulmonary parenchyma necrosis, it is a subacute lesion, since it was not encapsulated, we will not talk about pulmonary sequestration, which is a more chronic lesion. Microbiological culture allowed isolating grampositive, anaerobic bacteria with cocci and filamentous-bacilli morphology, compatible with Actinomyces sp.. In this type of lesion the most likely differential would have been a pulmonary abscess caused by T.pyogenes. If you had chosen this option it wasn't that wrong in the end! 😉
